Sweet's syndrome in patients with kidney and liver disorders.

Two patients with Sweet's syndrome are described. In the first patient the disorder was associated with urinary stone disease and in the second with chronic hepatitis. We compared skin lesions in patients with kidney and liver diseases with those in Sweet's syndrome.

Two cases of unilateral verrucous nevus.

We report two patients with epidermal nevus: one with linear verrucous nevus and one with inflammatory linear verrucous epidermal nevus. The patients first showed manifestations of nevus at different ages (soon after birth and at the age of seven), and the findings progressed differently. In both cases, warty plaques were located unilaterally, strictly following Blaschko's lines.

[A comparative study of the quantitative distribution and ultrastructure of Langerhans cells in the epidermis of patients with chronic benign dermatoses and mycosis fungoides].

Using histoenzymatic assay for ATPase activity and electron microscopy, Langerhans' cells (LC) in biopsy specimens taken from skin lesions of 20 patients with chronic benign dermatoses (CBD) and of 28 patients suffering from mycosis fungoides (MF) were identified. In the early lesions of MF the reduction of the number of cell dendrites, disappearance of normal arrangement and the reduced absolute quantity of LC were observed on comparison with patients with CBD. Ultrastructurally, the destroyed forms of LC were predominantly observed in MF lesions, while in cases of CBD most of the LC were functionally active.

[Sweet's syndrome].

A patient aged 50 with Sweet's syndrome combined with renal diseases is described. The clinical and pathomophological picture of the disease is described in detail. The skin process regressed after left percutaneous nephrostomy performed for the left ureter obstruction and after antibiotic and depuration therapy.

[Late ulcerating cutaneous leishmaniasis].

A female patient, aged 72, a resident of the endemic area in Uzbekistan, is described. She developed skin lesions on the face, resembling tuberculous involvement, two years before the condition has been diagnosed as cutaneous leishmaniasis with late ulceration. Leishmania have been isolated in laboratory studies.
