Sixteen patients with granular cell tumors were seen between 1964 and 1979. The medical data of these patients showed an average age incidence of 39 years and a greater frequency among Negroes (69%) and in female patients (62.5%). The most common sign (in 12 of 16 patients) was the presence of an asymptomatic mass. There was a total of 88 tumors in 16(More)
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(More)
Immune regulatory dysfunction, circulating immune complexes (CIC), and polymorphonuclear (PMN) cell migration were investigated in patients with Behçet's syndrome. Six patients meeting rigorous clinical criteria were evaluated. Only one patient showed evidence of immune regulatory dysfunction (increased T4/T8 ratio). Although C1q binding and Raji cell(More)
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(More)
A 38-year-old woman had a migratory silicone granuloma of the left upper portion of the chest and left upper arm secondary to a ruptured breast implant. The initial diagnosis was factitial panniculitis. With the common use of silicone in cosmetic surgery, physicians should inquire into a possible history of silicone injections or implants before ascribing a(More)
A recurrent, episodic illness that occurs in as many as 20% of patients who undergo ileojejunal bypass surgery for morbid obesity has been well characterized and includes inflammatory cutaneous lesions with a histologic appearance like that of neutrophilic vasculitis, a nondeforming polyarthritis, and other systemic manifestations. Current concepts of(More)
We present four cases of spreading pigmented actinic keratoses, an only recently described pigmented lesion of sun-exposed areas, in which the histologic appearance is that of actinic keratosis with the additional feature of excessive melanin deposition in the lower epidermis and in the upper dermis. Clinically, it is a brown patch or plaque with a smooth(More)
The usual methods of diagnosis remove Sarcoptes scabiei from its habitat. Thus, one has no appreciation of the host-endoparasitic interaction, especially the pathologic response of the surrounding tissue and the means by which the mite survives and lives its life cycle in the skin. The biopsy specimen described in this article demonstrates the tissue(More)
Two patients had distinctive adnexal skin tumors that showed cellular differentiation toward the formation of more than one adnexal structure. In one patient, the tumor showed differentiation toward pilar and sweat ductal structures. In the second patient, tumor differentiation toward the formation of sebaceous glands, pilar, and sweat ductal structures was(More)
