[Etiologic and epidemiologic study of dermatomycoses in Navarra (Spain)].

We review the etiology of the dermatophytosis in Navarra (Spain) over a 5-year period and it is compared with previous studies. We have isolated 312 strains of dermatophyte fungi in 285 patients (188 men and 97 women). Trichophyton rubrum was the most frequently isolated species (58.6%) followed by Trichophyton mentagrophytes (26.2%) and Microsporum canis (10.5%). Concerning the location of the lesions, tinea pedis was the clinical pattern found in the greatest number of patients, followed by tinea corporis, tinea unguium and tinea capitis. Twenty eight percent of the isolations were accomplished in October and November. More than half of those patients questioned had had epidemiological contact with animals or practiced sports. The rise of tinea pedis in our region is emphasised. The possible causes of this increment are analyzed and some recommendations for its control are made.

[Sweet's syndrome. Presentation of six cases and review of the literature].

The acute febrile neutrophilic dermatosis or Sweet syndrome, initially described in 1964 by Robert Sweet (1). It is characterized fever, neutrophilic leucocytosis, abrupt appearance of erythematous, painful, cutaneous plaquets and dense dermal infiltrate consisting of mature neutrophils without vasculitis sings. Malignancy has been described in the 10-15% of the reported cases. We report our series of 6 patients diagnosticated of this illness in our department. One of this patients has Sweet syndrome associated with a malignancy disorder. All of them had diagnostic criteria of the described disease and had good response to corticotherapy. We also report a bibliographic review of this infrequent syndrome.

Allergy to cow's milk with onset in adult life.

We report a 29-year-old patient with a history of asthma that is sometimes accompanied by urticaria, which is related to the ingestion of milk products. Once these were excluded from his diet no symptoms were observed. Skin tests, specific IgE, histamine release, and oral food challenges were positive to cow's milk and its fractions.

Epidermotropic primary neuroendocrine (Merkel cell) carcinoma of the skin with Pautrier-like microabscesses. Report of three cases and review of the literature.

Three cases of primary cutaneous neuroendocrine carcinoma involving the face are reported. In the first patient the tumor developed in the scar of a previously excised basal cell carcinoma of the nose, recurred locally, and metastasized to a regional lymph node 2 1/2 years after initial treatment. In the second and third patients the tumors were located on the forehead and were removed with a wide excision. In the second patient the tumor metastasized to regional lymph nodes 1 month after treatment. Light microscopic examination in all patients showed an undifferentiated, small cell, dermal tumor with prominent epidermotropism, forming Pautrier-like microabscesses. Immunohistochemical staining for neuron-specific enolase was positive, and ultrastructural examination revealed numerous cytoplasmic neurosecretory granules and paranuclear aggregates of intermediate-sized filaments. The literature concerning epidermal involvement by primary neuroendocrine carcinoma of the skin is reviewed; the relation with basal cell carcinoma and treatment are discussed.

Sebaceous gland hyperplasia of the vulva: a case report.

A unique case of sebaceous gland hyperplasia presenting as polypoid lesions on the vulva of a 32-year-old white woman is reported. Sebaceous hyperplasia is a benign condition most frequently seen on the forehead of elderly patients. The reported case presented with three soft, nontender polypoid lesions located on mons veneris and right labium majus. Histological examination showed hyperplastic sebaceous lobules not associated with hair follicles. The extremely rare site of the lesion, the clinical and histopathological differential diagnosis, and a therapeutical approach are discussed.

Urticaria pigmentosa. Histaminuria and treatment.

We present the case of an adult patient with urticaria pigmentosa. The sudden presence of severe symptomatology (symptoms to mast cell mediators release), made us think of evaluating extracutaneous affection. Our results are consistent with recent reports in the medical literature. We have confirmed an increase of conjugated histamine levels (methyl-histamine) during the attack and its return to normal values after the treatment. For these reasons we comment on the importance of histamine levels in diagnosis and treatment control. The gastrointestinal biopsy suggestive of mastocytosis; the severe clinical manifestations, and the histamine metabolite levels during the clinical course, led us to include this case in the group of "indolent SMCD" according to the TRAVIS classification.

Fine needle aspiration biopsy of myxoid metastasis of malignant melanoma.

The cytopathologic features of the fine needle aspiration biopsy of a myxoid metastasis of a cutaneous malignant melanoma are documented. The cytologic findings included fusiform-to-round cells with elongated cytoplasmic processes, fibroblastlike cells and inflammatory cells in a characteristic amorphous background substance. Immunocytochemical staining for S-100 protein was positive. The cytologic findings correlated well the histologic, histochemical, immunohistochemical and ultrastructural studies of the neoplasm. The cytologic differential diagnosis between metastases of malignant melanoma and other myxoid tumors of soft tissues is discussed.
