We report a 39 year old female, who 6 years later of accidental injury with cactus bristles, developed granulomatous lesions in her face with an ulcerative tendency. Histopathologic picture showed granulomatous infiltrates filling the full-thickness of the dermis, with abundant number of multinuclead giant cells foreign-body-type and Langhans-type and mixed inflamatory infiltrate. In the dermo-hipodermal limit, several foreing bodies were found with a thorny or barb shape, some of them into the giant cells, with were PAS positive and showed a brilliant refractile aspect under polaroscopic examination.

Harthnup disease clinical picture without aminoaciduria or other identified metabolic disturb (New entity?). The authors present a patient with clinical picture superposed to the Hartnup disease's, a rare, autosomic and recessive metabolic disturbance, characterized by typical aminoaciduria consequent to tryptophan and other neutral aminoacids defective transport by jejunal mucous membrane and renal tubules, clinically expressed by photosensitive pellagra-like dermatitis, mental retardation and intermittent cerebellar ataxia. The laboratorial results did not confirm Hartnup aminoaciduria nor other identified metabolic change that justify his clinical manifestations.

The authors present a study of hypersensitivity of patients with Hebra's prurigo (HP) to feleabites. Thirty six patients were studied. With the results obtained the following conclusions are held: 1. Among the probable responsible factors found in the history of patients with HP, the flea bite is the principal factor. 2. Almost all the patients with HP who were studied show hypersensitivity to flea bites. 3. With the flea bites on the patients with HP, one can observe the clinical and histopathology similarity of both the experimental and elementary lesions of the disease. 4. It was possible to show humoral antibodies in the serum of the patients with HP immunodiffusion technique to the 1:40 flea extract.

Trichodiscomas are hamartomas of the pilar apparatus, and have been described alone or associated to other benign proliferations of the pilar complex. Two familial cases of trichodiscomas not associated to pilar alterations or systemic manifestations are described.

It is presented a prospective study of vascular nevus during a year, with the finality to know its frequency, types and evolution. In twelve months of study, we founded in 1,485 borns that 14.14% presented those lesiones salmon stain 86%, oport wine 1.35%, capilar hemangioma or in strawberry the 10.81%, cavernous hemangioma the 0.45% and mixed hemangioma the 1.35%. Where more frequent in females that in males as well as from the urban zone in almost more than the half of the cases. Dimensions were between 0 to 5 cm. range, 98% in salmon stain, 95% in strawberry hemangioma, 66.3% mixed hemangioma, 66.6% in oport wine stain distributed in the head in more proportion. There was salmon stain in the nape in 61.7%, 15% in the forehead and in the superior eyelids 14.3%. The familiar antecedents of vascular nevus in brothers was of 4.76%, 5.71% in uncle, 2.98% in parents and 1.43% in grandparents. The evolution was not concluded because of desertion in almost the totality of patients, finalizing with only the 6.66%. Our findings are different from those published in the literature. The total frequency is more in our experience in salmon, oport wine stains and hemangiomas.

We record a case of systemic mastocytosis in a 70 year old male whose clinical picture started with abdominal symptomatology (pain and diarrhea) and syncopal episodes, who was found to have hepatosplenomegaly and skin, bone and bone-marrow involvement. Papulo-erythematous lesions appeared over the scar tissue of a previous colyscectomy. Scratching of these lesions produced urtication. Histologically an infiltration of mastocytes was found, being compatible with the diagnosis of systemic mastocytosis with Köebner's phenomenon. We review the most remarkable characteristics of systemic mastocytosis.

A new case of lymphocutaneous sporotrichosis is reported. We emphasize the low number of cases reported in the Spanish literature so far. We think that the incidence of this condition is higher than is reported. Because near all published cases had been published by the same authors who are familiarized and possess a high suspicion rate of this condition.

The Authors present a HIV-positive patient with atypical lesions of Granuloma annulare near the joints. Ten HIV-positive patients with Granuloma annulare have been reported until now in the world literature, and these cases are reviewed.
