[Interstitial brachytherapy in management of primary cutaneous melanoma: 4 cases].

BACKGROUND: Traditionally melanoma has been considered as a radioresistant tumor. However, recent observations regarding radiobiology and clinical response of melanoma have prompted physicians to re-evaluate the role of radiotherapy in the management of melanoma. Indeed, radiotherapy is frequently used in the treatment of metastatic melanoma but the role of this therapeutic approach in the primary tumor management is unclear. We report 4 cases of thick primary melanoma treated by interstitial brachytherapy. CASE REPORTS: Four patients (3 men, 1 woman; age: 73, 74, 79, 84 years), three with lentigo maligna melanoma and one with nodular melanoma, were treated exclusively by interstitial brachytherapy. The thickness of the 4 tumors was more than 3 mm. This treatment was chosen either because of the impossibility of conservative surgery or because of a contraindication for general anesthesia. Median follow-up was 48 months [18 to 65 months] and we did not observe any local tumor relapse. The cosmetic and functional results of this therapy were excellent. DISCUSSION: These four cases illustrate the possibility of obtaining good local control of thick primary melanoma by interstitial brachytherapy where surgery is impossible, although without challenging the standard surgical therapy for primary melanoma. Before our study, this treatment was used only in one study to treat melanoma patients. In this case however, interstitial brachytherapy was accompanied by surgery. Therefore, the findings reported here are the first to demonstrate the efficacy of this treatment when used as the sole treatment for primary melanoma. In conclusion, where surgery is difficult or impossible, interstitial brachytherapy may be used to treat primary melanoma with excellent local tumor control and a good cosmetic outcome.

[Familial case of Parkes Weber syndrome].

INTRODUCTION: Parkes-Weber syndrome is usually described as a sporadic form of osteohypertrophic angiodysplasia. However, family forms of Klippel-Trenaunay syndrome have been described. We report the first familial case of Parkes-Weber syndrome. OBSERVATION: A boy born at 27 weeks and 6 days of amenorrhea with extensive plane angioma of the right lower limb, right lower part of the back and abdomen. We also noted hypertrophy of this member with venous dilatations. Arterial Doppler ultrasound of the right lower limb showed an aneurysmal varix between the vein and the common femoral artery, confirming a diagnosis of Parkes-Weber syndrome. His maternal first cousin, 10 years his senior, also presented Parkes-Weber syndrome of the right upper limb. DISCUSSION: This is the first observation of a familial case of Parkes-Weber syndrome in first cousins. Vascular malformations are transmitted in autosomal dominant fashion in the majority of infected families but with incomplete penetrance and variable expressivity. Symptoms appeared to worsen from generation to generation. In each generation of this family, we noted the presence of hemangiomas or capillary malformations with aggravation in the third generation and onset of Parkes-Weber syndrome. Genetic investigation with linkage analysis for the various members in order to identify a predisposing locus yielded little of interest.

[Pneumomediastinum complicating the anti-synthetase syndrome].

INTRODUCTION: Pneumomediastinum is a rare but classical complication of dermatomyositis. Its development is a serious matter and necessitates prompt recourse to aggressive treatment with corticosteroids combined with immuno-suppressants or intravenous human immunoglobulin. CASE REPORT: We report the case of a 63 year old woman presenting with pulmonary infiltration, in the presence of dermatomyositis, as a clinical manifestation of the anti-synthetase syndrome. The progress was rapidly unfavourable with pneumomediastinum and acute respiratory distress despite initial treatment with corticosteroids followed by human immunoglobulin and immunosuppressants. CONCLUSION: The identification of cutaneous or muscular signs in the initial investigation of a pulmonary infiltrate should lead to a search for anti-synthetase antibodies in order to determine the optimal clinical management as quickly as possible.

[Celecoxib induced toxiderma with positive patch-test].

INTRODUCTION: Celecoxib (Celebrex(R)) is a new generation non-steroidal anti-inflammatory drug, recently introduced in France. We report a maculopapular rash due to this drug with positive patch-tests. CASE REPORT: A forty year-old man received with 3 tablets/day of celecoxib for intercostal pain. Nine days after initiation of treatment a maculopapular rash appeared. At the end of treatment, the eruption persisted for two days, then rapidly improved within one week. Six weeks later, patch-tests with celecoxib diluted at 20 p. 100 in petrolatum were positive at 48 hours. DISCUSSION: Cutaneous reactions due to celecoxib are rare. In our case report, the delay, clinical aspect, improvement on withdrawal of treatment and positive patch test all emphasize the imputability of celecoxib. We wish to underline the possible cutaneous reactions with this new non-steroidal anti-inflammatory drug.

[Ofuji's papuloerythroderma: two cases treated with azathioprine].

BACKGROUND: Ofuji's papuloerythroderma is a rare disorder, characterized by a generalized pruriginous eruption, sparing the folds. It predominates in the elderly. The pathology is still unknown but associations with lymphoma have been described. Various therapeutic approaches have been tried, most often including local and general corticosteroids and PUVA. OBSERVATION: Two patients aged 71 and 84 years presented red pruriginous macular rash sparing the abdominal folds. Eosinophilia and lymphopenia were observed. Cutaneous biopsies showed dermal lymphocytic and plasmocytic infiltrates with, in one case, eosinophil and neutrophil exocytosis. Clinical, biological and morphological investigations showed no association with other diseases such as cancer or lymphoma. Azathioprine permitted clinical and biological remission in both patients but had to be interrupted because of minor side effects (infection, gastroenterologic disorders) and corticosteroids were introduced in one case. DISCUSSION: We suggest that histological aspects, such as exocytosis, may represent a link between Ofuji's papuloerythroderma and lymphoma. Azathioprine led to clinical and biological improvement in our 2 patients. Because of its adverse effects, it could be proposed as second-line therapy in patients presenting resistance or intolerance to usual treatments.

Keratosis lichenoides chronica: report of a new case, with success of PUVA therapy.

Keratosis lichenoides chronica is a rare disorder. It consists of the progressive development of asymptomatic verrucosities on the limbs and the trunk, with a partially linear distribution. We report the case of a 78-year-old woman who presented with keratotic plaques and papules of the trunk and the limbs for several years. A diagnosis of keratosis lichenoides chronica was clinically and histologically evident. PUVA-therapy was started, with excellent results.

[Toxic dermatitis caused by tramadol].

BACKGROUND: Tramadol chlorhydrate (Topalgic) is a powerful analgesic recently introduced in France where its use has spread rapidly. We report a case where this drug induced a maculopapulous toxic skin reaction with secondary erythrodermia. CASE REPORT: A 47-year-old man was treated for lower back pain with tramadol chlorhydrate (50 mg b.i.d.). Otherwise, he was in good general health and was taking no other medications. Shortly after beginning the treatment, he developed a highly pruriginous maculopapulous eruption involving the entire skin surface, hyperthermia and general degradation. There was no skin exfoliation, mucosal involvement nor nodal enlargement. Tramadol was withdrawn and the patient was given corticosteroid therapy. Secondary erythrodermia developed after termination of the corticosteroids. The lesions regressed after tramadol withdrawal. DISCUSSION: Tramadol-induced skin reactions are uncommon and usually benign. In our case, the delay from onset of tramadol and the development of the maculopapulous eruption was very short (four days). The patient was taking no other medication. We hypothesize that the patient had been sensitized by cross-reaction with another compound and recall the fundamental aspects of tramadol and opiate drugs.

[Symmetrical benign lipomatosis of the tongue and Launois-Bensaude lipomatosis].

BACKGROUND: There are many causes of macroglossia, including fatty infiltration. Unlike unique or multiple lipomas of the tongue, non-encapsulated adipocyte masses develop in the tongue in symmetrical benign lipomatosis. Only six cases have been reported in the literature. CASE REPORT: A 69-year-old man with a history of chronic alcoholism developed a soft tumefied formation on the lateral margins of the tongue. A yellow-colored content was perceived through the thin mucosa. The formation was bilateral and had developed for more than 10 years. The patient also presented Launois-Bensaude lipomatosis localized on the neck, the nuchal region and the shoulders. DISCUSSION: This is, to our knowledge, the first reported case of symmetrical benign lipomatosis associated with Launois-Bensaude lipomatosis. An analogy between these two conditions has been suggested, but the six earlier cases of lipomatosis of the tongue reported in the literature developed in patients without cutaneous lipomatosis.

[Leg ulcers and antiphospholipid antibodies. Prospective study of 48 cases].

BACKGROUND: Leg ulcres can be seen as manifestations of antiphospholipid syndromes but their pathogenic relationship with vascular thrombotic events secondary to antiphospholipid antibodies remains to be defined with precision. A significant association between anticardiolipin antibodies and venous leg ulcers has been described. We conducted this study to determine whether such an association is found in venous ulcers and if it could also be present in cases involving the arterial and/or arteriolar circulation. PATIENTS AND METHODS: From December 1995 to March 1997, 48 patients with leg ulcers involving venous (27 cases), arteriovenous (9 cases) or arteriolar (12 cases) circulations were admitted. The etiologic diagnosis was based on clinical presentation and duplex Doppler findings examining the superficial and deep venous and arterial circuits. Antiphospholipid antibodies were searched for in all cases: VDRL, ELISA for IgG and IgM antiphospholipid antibodies, antiprothrombinase circulating anticoagulant. RESULTS: Circulating anticoagulants were found in 22 of the 48 patients (46%): 12/27 (44%) involved venous leg ulcers (anticardiolipin antibodies, 5 cases; circulating anticoagulants, 4 cases; both, 2 cases); 1/9 involved arteriovenous ulcers (anticardiolipin antibodies, 5 cases); 9/12 involved arteriolar ulcers (anticardiolipin antibodies, 3 cases; circulating anticoagulants, 6 cases; both, 3 cases). Seven of the 9 patients also had severe arteritis. A past history of venous thrombosis was found in 3 cases with venous ulcers and antiphospholipid antibodies. One patient among the 5 with arteriolar ulcers had a past history of arterial thrombosis. DISCUSSION: Our cohort is too small for a formal conclusion but underlines two points: 1. antiphospholipid antibodies can be associated with venous ulcers independently of thrombosis history. The hypothesis that leukocyte stasis and endothelial cell activation causes an immune reaction implicating antiphospholipid antibodies has been put forward. The usefulness of an antiaggregate treatment or an anticoagulant treatment should be discussed, 2. The possible association between arteriolar ulcers and antiphospholipid antibodies requires further large scale studies.

Bullous pemphigoid in association with cutaneous lesions specific to a myelodysplastic syndrome.

Specific cutaneous lesions are a rare occurrence in myelodysplastic syndromes (MDS). The concurrent association of blistering skin lesions similar to those in bullous pemphigoid (BP), even though a rare event, suggests that BP may be a paraneoplastic syndrome. We report an 86-year-old man who had a refractory anaemia with excess bone marrow blasts in transformation, who developed a generalized pruritic blistering eruption. Immunohistopathological tests showed subepidermal blisters with linear deposits of IgG and C3 along the basement membrane zone of the epidermis surrounding a tumoral dermal infiltrate of CD13+ and CD15+ cells. Immunoblotting studies using epidermal extracts revealed circulating IgG antibodies against three protein bands: a 210-215 kDa band, a 180 kDa band which co-migrated with the BP 180 antigen, and a 190 kDa band. The tumour infiltrate may have revealed antigenic determinants which led to the onset of BP. The concept of paraneoplastic pemphigoid remains to be either confirmed or invalidated by further epidemiological studies.

[Chronic sclerodermiform syndrome disclosing subcutaneous T-cell lymphoma].

INTRODUCTION: Subcutaneous tissue is an uncommon primary localization for T-cell lymphomas. Panniculitis with recurrent papulonodules are reported in most cases. CASE REPORT: We report a case in which small-cell pleiomorphic non-Hodgkin lymphoma developed initially in subcutaneous tissue followed by secondary systemic extension. The first clinical manifestation was a sclerodermiform syndrome involving the four limbs. DISCUSSION: This type of lymphoma appears to have a polymorphic clinical presentation. Physicians should be aware of this type of lymphoma and use immunohistological techniques for early diagnosis.
