[Cranioencephalic cutaneous angiofibromatosis].

A nine year old girl with no significant prenatal or perinatal history had presented, at the age of four months, with infantile spasms and later with partial crises with or without secondary generalization. On examination there was left hemiparesis and various skin lesions: a pink plaque in the frontal region with hair loss, fibrous plaques on the right side of the face and hypomelanic spots on the trunk and thighs and some cafe-au-lait spots on the thorax and abdomen. On neuroimaging by CT and MR right cerebral hemiatrophy, periventricular calcifications and lesions in the right hemisphere were seen. On AMR an angioma was seen on the anterior communicating artery. A skin biopsy of the frontal plaque showed perifollicular fibromatosis with marked vascular proliferation. We discuss whether the presentation of this case of encephalocraneo-cutaneous angiofibromatosis is a new phenotype of tuberose sclerosis or a new neurocutaneous syndrome.

Cutaneous sarcoid granulomas with oat cell carcinoma of the lung.

A case of a 68-year-old male is presented, with a history of asymptomatic slight scaling, infiltrated patches with an atrophic central portion, of 3 months of evolution on the face and trunk. A chest X-ray showed an oat cell lung carcinoma, with the same evolution time as the cutaneous lesions. Several cutaneous biopsies showed typical sarcoid granulomas, with profuse giant cells. An immunohistochemical study showed B-cell-positive granulomas. The patient was treated with cytostatic drugs and prednisone, leading to cutaneous, radiological and clinical complete regression of the lesions. We think that this case corresponds to a tumor-related cutaneous sarcoid granuloma reaction.

[Kerion Celsi. A diagnostic problem? Experience with 6 cases].

We report six patients with Kerion Celsi due to Trichophyton verrucosum. Five of the patients were hospitalized with the diagnosis of Staphylococcal abscess. This confusion is due to that highly suppurative and inflammatory nature of the infection. Griseofulvin is the antimicrobial of choice for treatment, associated with imidazolics and corticosteroids to prevent alopecia. The authors suggest that an adequate use of simple microbiological diagnostic tests in the diagnosis of pyodermitis in rural children, may prevent unnecessary hospitalizations and permanent hair loss.

Congenital insensitivity to pain with anhidrosis.

A nine-year-old child presented with congenital insensitivity to pain and anhidrosis. Quantitative studies and electron microscopy of the cutaneous branch of the radial nerve revealed almost complete absence of small myelinated and unmyelinated fibers and a disproportionate number of nerve fibers with a diameter of 6-10 micrometers. A grouping of both type 1 and type 2 muscle fibers was also seen. We suggest that this disease entity is not caused by a hereditary sensory neuropathy, but rather that it derives from a developmental defect.

Conradi-Hünermann syndrome with unilateral distribution.

Conradi-Hünermann syndrome is a type of chondrodysplasia punctata characterized by skeletal, cutaneous, and ocular anomalies. Genetic heterogeneity and incomplete penetrance may explain the wide clinical spectrum. We report a 7-day-old girl, product of a preterm pregnancy and delivery, with ichthyosiform erythroderma on the right half of the body at birth, as well as patchy cutaneous involvement of the contralateral side. On physical examination, we observed an ipsilateral shortening of the leg and a lenticular opacity of the right eye. Histopathologic study showed parakeratotic hyperkeratosis with prominent follicular involvement and atrophy of the granular and spinous layers. The skin eruption disappeared during the first 2 months. At 2 months of age, radiologic examination revealed stippled calcifications in the ribs, vertebral, and paravertebral areas. The most important differential diagnosis was CHILD syndrome. We emphasize the importance of the histopathologic study in the differential diagnosis of both syndromes.
