Tumorlike eosinophilic granuloma of the skin.
In 1952, Kuske reported on a patient with a peculiar tumor on the dorsum of the right hand; histological analysis revealed a dense dermal infiltrate with numerous eosinophils. Not aware of any similar case report in the literature, he coined the descriptive term "tumor-like eosinophilic granuloma of the skin." In 1995, a 55-year-old white man with cancer of the prostate presented with a 4-month history of two reddish-brown, solid skin tumors on his left forearm and on the right side of his abdomen, respectively. Histologic examination revealed a dense, superficial and deep, tumorlike dermal inflammatory infiltrate consisting mainly of eosinophils as well as neutrophils and in part epithelioid, in part foamy histiocytes. Flame figures were absent. Immunohistochemical analysis was negative for S-100 protein, whereas sporadic cells in the infiltrate were CD1a positive and many mononuclear-histiocytic cells reacted with MAC 387. Stains as well as cultures for bacteria, mycobacteria, and fungi were negative. The descriptive diagnosis of tumorlike eosinophilic granuloma of the skin was made. Seven weeks after prostatectomy, both tumors resolved spontaneously and so far has not recurred. In our opinion, this is the second report of Kuske's tumorlike eosinophilic granuloma of the skin. Perhaps tumorlike eosinophilic granuloma of the skin, eosinophilic ulcer of the mucosa, and transient eosinophilic nodulomatosis should be considered a mucocutaneous reaction pattern as is seen in cats. In humans, hypersensitivity reactions or atopy could emerge as an etiological link.
