Pemphigus vegetans of Hallopeau: immunofluorescent studies.

Immunofluorescent techniques were used in the study of tissue from a patient with pemphigus vegetans of Hallopeau. The findings were typical of pemphigus, confirming the propriety of classifying this entity as a benign variant of pemphigus, rather than a disease of purely microbial etiology. The question is raised whether other types of vegetating pyodermas actually are separate diseases or represent a spectrum of pemphigus with the clinical appearance dependent on the patient's immunity to his disease. Immunofluorescent studies are proposed as a basis for classification.

Acral syringoma.

Although syringoma is a relatively common adnexal tumor, syringoma of the hands has not been reported previously. We report a unique case of multiple acral syringomas that appeared as symmetrical grouped erythematous papules limited to the dorsum of the proximal and middle phalanges of both hands in a young man. This condition should be considered in the diagnosis of papular lesions of the hands.

Subcutaneous fat necrosis associated with pancreatic disease.

Subcutaneous fat necrosis, a type of panniculitis, is a rare entity that is manifested by painless or painful subcutaneous nodules on the legs, buttocks, or trunk and is associated with pancreatitis or carcinoma of the pancreas, either of which may be asymptomatic. The histopathological findings are pathognomonic and consist of subcutaneous focal fat necrosis and "ghost-like" cells with thick, shadowy walls and no nuclei. Arthritis, particularly of the ankles, is a commonly associated finding. Distant foci of fat necrosis in pancreatic disease are probably due to the local action of hematogenous-borne trypsin and lipase. Since the underlying pancreatic disease may be asymptomatic, histopathologic study of all cases of panniculitis should be considered.

Dermal duct tumor.

A dermal duct tumor occurred on the left leg of a 66-year-old man. The lesion first occurred as a solitary lobulated tumor of approximately 20 years' duration. This apparently brings the total number of recorded cases to 12. It is believed to be a benign tumor of the intradermal portion of the eccrine sweat duct and is distinctive and diagnostic histologically. The spectrum of benign tumors of the eccrine sweat duct epithelium includes hidroacanthoma simplex or intraepidermal eccrine poroma, eccrine poroma, and dermal duct tumor.
