Cutaneous lesions arising during the course of chronic lymphocytic leukemia (CLL), generally of the B-cell type, are frequent. Three types of cutaneous manifestations must be differentiated: (1) specific lesions, (2) cutaneous manifestations closely related to the disease but without a leukemoid infiltrate and (3) associations with various dermatologic conditions. The various clinical features are discussed.

Four cases of cutaneous rash, clinically more or less similar to erythema multiforme have been observed in patient who either stayed in a room with an accidentally high content of fluorocarbons, or had a skin contact with butane or phenyl-azo-beta-naphthol. The cutaneous lesions appear to be secondary to absorption of the toxic product, and probably induced by inhalation rather than by percutaneous penetration. Arguments for the responsibility of the substances rely on anamnestic data.

Occurrence of basal cell epithelioma and syringocystadenoma papilliferum on sebaceous nevi is well known. But many other adnexal tumors, such as pilar or sweat gland tumours may also be associated with this dysembryoplasia. Out of 99 cases of verruco-sebaceous nevi we find 12 associated basal cell epitheliomas, 7 syringocystadenomas papilliferum and 6 benign adnexal tumors. Our report is about these 7 cases. All of these tumors appeared in adult-hood and were clinically suggesting the diagnostic of basal cell epithelioma. But, after histopathological examination was performed, they revealed to be 2 nodular hidradenomas, 1 chondroid syringoma, 1 trichilemmoma, 1 apocrine cystadenoma, 1 follicular poroma. Similar data are given by Mehregan and Pinkus in 1965 and Wilson Jones and Heyl in 1970, respectively out of 150 and 140 cases of verruco-sebaceous nevi.

Diabetes insipidus is the most common endocrine disturbance associated with chronic multifocal form of histiocytosis X. Involvement of the hypothalamus can lead to growth hormone deficiency and short stature in children. Two cases with hypogonadism, growth hormone deficiency and diabetes insipidus are reported. In a 22-year-old man plasma testosterone was low and increased after administration of human chorionic gonadotrophin. Cutaneous and lytic bone lesions disappeared after treatment with Vinblastin. Partial diabetes insipidus was treated with clofibrate. A 59-year-old woman was found to have low pituitary gonadotrophins that failed to rise after administration of gonadotropin-releasing hormone and hyperprolactinemia. Fatal outcome was associated with polyuria, bone, cutaneous, gut and hypothalamic infiltration by histiocytes. There was no direct involvement of the anterior pituitary gland.

In 1971, four cases of a new dermatosis were described by Wells, under the name of recurrent granulomatous dermatitis with eosinophilia. In 1978, eight additional cases were reported by Wells and Smith and three authors suggested a shorter title: eosinophilic cellulitis for this syndrome. Since then, four additional cases were published in the literature. We report here two additional cases. From these eighteen upto now published cases, there is no doubt that this dermatosis, as initially described by Wells, is a distinct entity. Clinical course is characterized by sudden eruption of large infiltrated, itchy and/or painful plaques. Blisters are often associated. During the two or three weeks following the initial rash, the inflammatory aspect disappears. Lesions become indurated, and may resemble morphea. Spontaneous resolution occurs after about six weeks. Recurrences are constantly observed. Histologic features are a striking eosinophilic infiltrate associated with eosinophilic deposits constituting flame figures. Blood eosinophilia is present in most cases. Etiology of this entity remains unknown.
