[Diffuse gingival plasmocytoma: a rare location of extra-osseous solitary plasmocytomas (author's transl)].

A 51-year-old man presented with isolated diffuse gingival hypertrophy, the diagnosis of a plasmocytoma being suspected after pathological and immunohistological examinations of a gingival biopsy (light chain lambda plasmocytes). The isolated nature of this diffuse gingival plasmocytoma was confirmed by biological tests and radiological investigations. The evolution of solitary plasmocytomas is variable, and while certain of these lesions remain isolated even after many years, other plasmocytomas, apparently local, are associated with myelomas which either become evident or may sometimes develop. The extremely rare nature of diffuse gingival locations of extra-osseous solitary plasmocytomas is confirmed by a review of the published literature. Studying histological sections by immunofluorescence enables the polyclonal or monoclonal nature of the plasmocytes to be established, this distinction being an important element in the prognosis.

[Wegener's granulomatosis and pregnancy. A case].

Pregnancy concomitant with Wegener's granulomatosis is extremely rare: so far, only four cases have been published. The authors report a fifth case where the disease appeared during the post-partum period, a situation which has already been noted in two of the published cases. Interruption of a subsequent pregnancy was followed by a flare-up of the disease resulting in the patient's death. This suggests that post-partum and post-abortum are probably instrumental in the onset and deterioration of Wegener's granulomatosis. The two patients previously reported who received immunosuppressants combined with corticosteroids had no flare-up after delivery. It seems permissible to prescribe such a therapeutic combination before and after delivery or abortion, especially since the fear of foetal toxicity from these drugs seems to be exaggerated.

Bullous pemphigoid in a leg affected with hemiparesia: a possible relation of neurological diseases with bullous pemphigoid?

We report a typical case of bullous pemphigoid (BP) associated with a neurological disorder and study a possible link between neurological disorders and BP. An 84-year-old hemiplegic woman presented with unilateral BP on the hemiparetic side. BP was confirmed by histological and immunofluorescence data. The medical records of the previous 46 consecutive patients with BP were retrospectively analyzed (average age: 79; median age: 85). Thirty of the 46 patients with BP had neurological disorders. These disorders included dementia, epilepsy, multiple sclerosis, cerebral stroke, Parkinson's disease, gonadotropic adenoma, trembling, dyskinesia, lumbar spinal stenosis. In a control group of the 46 consecutive oldest patients (older than 71; average age: 82,5; median age: 80) with another skin disease referred during the previous two-year-period to our one-day-unit only, 13 patients had a neurological disorder. This study demonstrates that there is a high prevalence of neurological disorders in patients with BP (p = 0.0004). A prospective case control study with neurological examination and psychometrical evaluation is warranted to confirm these data. We speculate that neuroautoimmunity associated with the aging process or neurological disorders may be involved in pemphigoid development via an autoimmune response against dystonin which shares homology with bullous pemphigoid antigen 1. Bullous pemphigoid could be considered to be a marker of neurological disorder.

[Epithelioma cuniculatum. Apropos of a case with review of the literature].

A case of Epithelioma cuniculatum arising on a leg ulcer in a 85 years old lady is described. 102 cases have been reported before, mainly located on the sole of the foot: this rare tumor may be recognized by the gross appearance of a slow-growing exophytic cauliflower growth, exuding foul smelling material from numerous sinuses, which eventually invades underlying tissue sometimes including bone, and which rarely metastasizes to the regional lymph nodes. Histological examination shows a well-differentiated squamous epithelial proliferation without cellular atypia, with numerous crypts and sinuses. The diagnosis is difficult as the cytological regularity does not allow malignancy to be evoked. It is the conspicuity of the invasion of the deep tissues with sufficiently large samples that makes it certain. The differential diagnosis includes keratoacanthoma, pseudo-epitheliomatous hyperplasia mainly represented by pyoderma vegetans and "classical" squamous cell carcinoma. From a nosological point of view the authors totally assimilate Epithelioma cuniculatum and Gottron's papillomatosis cutis carcinoïdes regrouped under the name of cutaneous verrucous carcinoma, emphasizing the analogy with verrucous carcinomas of mucous membrane, giant condyloma of Buschke-Lowenstein, oral florid papillomatosis.
