Panniculitis in tuberculosis: a clinicopathologic study of nodular panniculitis associated with tuberculosis.

BACKGROUND: Certain types of panniculitis, erythema induratum of Bazin and erythema nodosum, have been well documented as tuberculids. Many histopathologic diagnoses of panniculitis have been reported in tuberculosis patients. This study investigates the correlation between underlying tuberculosis and clinicopathologic findings of panniculitis. METHODS: We retrospectively reviewed the clinical files of histologic-proven panniculitis cases at the Dermatologic Clinic, Siriraj Hospital from January 1992 to December 1995; only cases with active tuberculous foci were analyzed. RESULTS: The incidence of panniculitis caused by tuberculosis was 8.2%. The ratio of men to women was 1:1. The mean age of onset was 35.3 years. The average duration of the nodules was 35.5 days. There was a history of contact tuberculosis in 16.6%. Constitutional symptoms and a strongly positive purified protein derivative (PPD) reaction were found in 66.6%. Chest roentgenograms were abnormal in 83.3%. The erythrocyte sedimentation rate was elevated in all tested cases. The histopathologic diagnoses were nodular vasculitis (33.3%), erythema nodosum (50%), and cutaneous periarteritis nodosa (16.4%). The panniculitis lesion responded to standard antituberculous regimens in 4.6 weeks, on average, with residual hyperpigmentation. CONCLUSIONS: In panniculitis patients, clues for the investigation of tuberculosis included constitutional symptoms, elevated erythrocyte sedimentation rate, and abnormal chest roentgenograms. Histopathologic changes of panniculitis did not seem to correlate with underlying tuberculosis. The clinician should be aware of the tuberculosis, however, and should carefully search for active foci in all panniculitis patients.

The clinical spectrum of lipoatrophic panniculitis encompasses connective tissue panniculitis.

Two patients with widespread, chronic, relapsing panniculitis resulting in disfiguring lipoatrophy are reported. Histology in both cases showed a mixed septal and lobular panniculitis, with lipophagia. The clinical appearance and histology suggested a diagnosis of lipoatrophic panniculitis. Both cases had features of connective tissue panniculitis, which is likely to be a subtype of this condition. Treatment of lipoatrophic panniculitis can be difficult. Our first patient initially responded well to antimalarial therapy, allowing plastic surgical repair of the defects to be carried out.

Panniculitis of pancreatic disease masquerading as systemic lupus erythematosus panniculitis.

We describe a patient with systemic lupus erythematosus (SLE) who presented with severe refractory pannicular lesions diffusely involving the buttocks and lower extremities. Due to the severity of these lesions, a biopsy was performed, which implicated panniculitis associated with pancreatic disease, rather than lupus panniculitis. Serum amylase was normal, but the serum lipase was markedly elevated. An abdominal computerized tomographic scan demonstrated a pancreatic mass, which upon laparotomy was found to be an acinar cell carcinoma. After resection of the mass, her symptoms improved, where they had not responded to prior immunosuppressive therapy. She has subsequently remained well without recurrence of the disease. This case illustrates that an uncharacteristic presentation of panniculitis in a patient with lupus does not necessarily imply lupus panniculitis, and a biopsy is imperative to distinguish other sometimes life threatening etiologies.

Septal granulomatous panniculitis: comparison of the pathology of erythema nodosum migrans (migratory panniculitis) and chronic erythema nodosum.

Fifty-eight cases of septal granulomatous panniculitis were reviewed; 14 cases were diagnosed as erythema nodosum migrans (migratory panniculitis) and 36 as chronic erythema nodosum on the basis of clinical and histopathologic features. Erythema nodosum migrans was characterized by markedly thickened and fibrotic septae, marked capillary proliferation (like granulation tissue), and massive granulomatous reaction (with giant cells) along the borders of the widened septa. Hemorrhage was rare, and phlebitis was not seen. Chronic erythema nodosum showed mild septal change, little fibrosis, and lymphohistiocytic perivascular inflammation with only focal granulomatous formation. Phlebitis and hemorrhage were common. The condition termed erythema nodosum migrans has many of the same clinical features as chronic erythema nodosum, and we think this term is preferable to migratory panniculitis. We believe that there are sufficient clinical and histopathologic features to justify considering erythema nodosum migrans as a unique clinicopathologic entity.

An experimental model of fasciitis-panniculitis. Induction of chronic fibrosing panniculitis in the rat by subcutaneous injections of lipase.

We describe an experimental model of the fasciitis-panniculitis syndrome, which includes eosinophilic fasciitis and its related disorders. Rats were given a single or repeated subcutaneous injections of saline or a 10% lipase solution. The injection sites were studied histologically and histomorphometrically. With few exceptions, the subcutaneous-fascial unit of the saline-injected rats was normal. An acute necrotizing panniculitis with inflammatory involvement of the adjacent fascia was found 2 days after a single injection of lipase. Three to 6 weeks after a single injection of lipase, the subcutaneous fat tissue and fascia were fibrotically thickened and chronically inflamed. Similar but more advanced alterations had developed in animals killed 3 weeks after three weekly injections of lipase. Progressive fibrotic thickening of the subcutaneous-fascial unit was observed following an increasing number of weekly lipase injections. The acute-phase reaction expresses a pattern of steatonecrotic tissue damage. In the ohronic phase, the fibrotically thickened subcutaneous layers typify a reaction pattern analogous to that of the human fasciitis-panniculitis syndrome. This experimental model permits better appreciation of the disorder's nonspecific pathogenesis and may help in the search for alternative therapeutic modalities.

Cytophagic histiocytic panniculitis--a syndrome associated with benign and malignant panniculitis: case comparison and review of the literature.

Many cases of hemophagocytic syndromes with cytophagic histiocytic panniculitis (CHP) are being classified and considered as a natural disease progression of subcutaneous panniculitic T-cell lymphoma (SPTL). Review of the literature on both CHP and SPTL discloses distinct patterns suggesting these disorders may not be equivalent, even though a terminal hemophagocytic syndrome may be associated with each. Some SPTL appear to have association with Epstein-Barr virus (EBV), show malignant histopathology in the skin, and may disseminate terminally, with a majority of cases showing a rapidly fatal progression. On the other hand, classic cases of CHP without proven lymphoma may not be associated with EBV, appear to be histologically benign, and have an indolent course unless terminal hemophagocytic syndrome develops. We compared and contrasted a case of CHP and a case of SPTL and reviewed the literature. Our observations suggest that the often fatal hemophagocytic syndrome may be associated with both benign and malignant subcutaneous panniculitis.

[Necrotizing panniculitis of the colon--a rare form of mesenterial panniculitis].

A 37-year old man was admitted with colics in the upper right abdomen. Since the laparoscopy revealed a massive thickening of the right colonic flexure a hemicolectomy was performed. The histologic examination yielded the diagnosis of a necrotizing panniculitis of the colon, a rare variant of mesenterial panniculitis usually occurring in the small intestine. Signs and symptoms, diagnostics, and therapeutic approaches of this disorder of unknown cause are discussed.

Acute lipase-induced panniculitis in rats with ligated veins of the hindlimb: a contribution to the role of acute panniculitis as a precursor of lipodermatosclerosis of venous disease.

The authors studied the effect of ligation of the femoral and saphenous veins on the evolution of lipase injection-induced subcutaneous fibrosis and inflammation in the rats' hindlimbs. The superficial muscular fascia was thickened and the number of veins was increased 3 days and 3 weeks after vein ligation; both abnormalities disappeared 6 weeks postoperatively. Vein ligation did not quantitatively affect fascial thickening or fibrosing panniculitis in hindlimbs injected with lipase 6 weeks prior to sacrifice. The results contradict the proposition that lipase-induced injury of rats' subcutaneous tissues compromised by venous stasis may lead to a persistent chronic inflammation and fibrosis of the subcutaneous-fascial complex duplicating lipodermatosclerosis in man.

[Panniculitis with cellular phagocytosis. Chronic form of histiocytic panniculitis with fever, pancytopenia, polyserositis and lethal hemorrhagic diathesis].

Two cases of what was originally called "Weber-Christian disease" were found to be a chronic, recurrent form of histiocytic panniculitis characterized by histiocytic engulfment of red and white blood cells--"cytophagocytosis." The disease was manifested by recurrent fever, subcutaneous nodules, pancytopenia, and mucosal ulcerations. Hepatosplenomegaly and enlarged lymph nodes were observed. Focal invasion of the reticuloendothelial system by acidophilic or cytophagic histiocytes could be identified. Progressive changes in liver function and hemorrhagic diathesis occurred in both patients.

Povidone panniculitis. Polyvinylpyrrolidone panniculitis.

Multiple subcutaneous nodules and recurrent flu-like episodes developed in a 60-year-old woman after she had received local intramuscular injections of procaine povidone for a seven-year period. A skin biopsy specimen showed distinctive gray-blue material in the histiocytes in sections stained with hematoxylin-eosin. Povidone is an inert substance that may accumulate in multiple organs, including the skin. Its presence can be verified by its affinity for special stains or by spectrophotometric analysis. In our patient, ultrastructural study showed amorphous inrahistiocytic deposits in the tissues. -revious reports have indicated that this substance may eventually accumulate in noninjected skin sites and may lead to pulmonary and arthritic symptoms in some patients, but no other patients, to our knowledge, have had complications associated with fever.

Weber-Christian panniculitis: a review of 30 cases with this diagnosis.

BACKGROUND: More than 60 years ago, Christian described a panniculitis that was later termed Weber-Christian disease. OBJECTIVE: The purpose of this study was to investigate whether this is a specific disease or a nonspecific disease that embraces several specific conditions. METHODS: We studied 30 cases diagnosed as Weber-Christian panniculitis and found it possible to make a more specific diagnosis. RESULTS: In 12 patients, findings were compatible with erythema nodosum. Six patients had phlebitis or postphlebitic syndrome. Factitial panniculitis was diagnosed in five patients, and trauma had a role in the conditions of another three patients. Cytophagic panniculitis, lymphoma, and leukemia were recognized in one patient each. The lesion was lobular in almost all cases, and the presence of lipophagia was noted in 19 biopsy specimens. Granulomatous, neutrophilic, and lymphocytic pathologic changes were present in nine, eight, and eight tissue specimens, respectively. CONCLUSION: The recognition of distinct disease patterns of fat lesions as fat necrosis with pancreatic disease, alpha1-antitrypsin panniculitis, lupus and connective tissue disease panniculitis, involution lipoatrophy, lipomembranous panniculitis, factitial panniculitis syndromes, calcification panniculitis, lipophagic lipoatrophy, and cytophagic panniculitis has lessened the need for a less specific panniculitis category. All these diseases have been reported in the literature as "Weber-Christian disease." Because separate and distinct forms of fat lesions have been described, we believe that the eponym should be abandoned and that more specific diagnoses should be made on the basis of pathogenesis or cause.
