Cutaneous manifestations of tumoral calcinosis.
We have followed up a large family in which seven members have tumoral calcinosis. One girl had the skin lesions of localized calcinosis cutis apart from the typical subcutaneous deposits of calcium. Like most persons with tumoral calcinosis, our patient had normal serum calcium concentrations; however, the serum phosphorus levels were greatly elevated. The familial occurrence and elevated serum phosphorus levels suggest the possibility of some as yet undefined, heritable metabolic defect as the underlying cause. The occurrence of tumoral calcinosis with localized calcinosis cutis is a rare association, and there has been only one other reported case to our knowledge. This report describes our patient and offers a brief discussion of tumoral calcinosis. The therapeutic response to the phosphate depletion regimen and topical steroids was disappointing in our case.
Toxic epidermal necrolysis from graft-vs-host disease. Occurrence in a patient with thymic hypoplasia.
An infant with diarrhea, failure to thrive, and a seborrhea-like skin eruption was thought to have fatal familial Leiner's syndrome. Treatment with nonirradiated plasma was followed by graft-vs-host disease and fatal toxic epidermal necrolysis; thymic hypoplasia was found at autopsy. Accurate diagnosis of immunodeficiency syndromes is essential to avoid potentially harmful therapy.
Febrile neutrophilic dermatosis in acute myelogenous leukemia.
A 50-year-old woman with acute myelogenous leukemia on two occasions had fever and exquisitely tender, warm, erythematous, indurated to frankly bullous plaques on the face and upper extremities. Histologically, the lesions showed rather dense dermal infiltrates of mature polymorphonuclear leukocytes; special stains for bacteria and fungi were negative, as were all cultures for infectious agents. The lesions did not respond to antibiotics but cleared rapidly with systemic steroid treatment. Febrile neutrophilic dermatosis of acute myelogenous leukemia is believed to be a nonspecific reaction to the underlying malignant disease process. By prompt recognition of this entity, prolonged expensive courses of antibiotics may be avoided.

Dysplastic nevi of the scalp and forehead in children.
To determine if there is a significant difference in the relative frequency and degree of atypia of sporadic dysplastic nevi from the scalp, face, and neck area in children as compared with nevi from the rest of the body, we reviewed 99 consecutive biopsy specimens of melanocytic nevi from the scalp, face, and neck areas in children less than 18 years of age and compared them with 95 consecutive cases of nevi from other areas of the body in children of the same age. Large numbers of the nevi biopsied from the scalp (13 of 31; 41.93%) and forehead (2 of 10; 20%) were dysplastic. The number of dysplastic nevi from the neck (1 of 58; 1.72%) was not assessed as very different from the incidence found in other regions of the body, where 7 dysplastic nevi (7.36%) from a total of 95 nevi were found. Of the 13 dysplastic nevi from the scalp, 9 showed minimal atypia and 4 showed moderate atypia. No nevi with severe atypia were found. Many pigmented nevi from the scalp and forehead in children in this study were dysplastic. This finding points out the importance of examining the scalp of children for the presence of dysplastic nevi. The majority of nevi from the neck were common nevi.

Nonlipidized juvenile xanthogranuloma: a histologic and immunohistochemical study.
Among all patients with a pathologic diagnosis of juvenile xanthogranuloma (JXG) seen at our institution from 1983 to 1994, we identified five patients with an unusual histologic pattern that differed from the classic juvenile xanthogranuloma (CJXG) with foamy cells and Touton giant cells. Four of these five cases, which we termed nonlipidized juvenile xanthogranuloma (NJXG), were seen in infants. The histologic features include a monomorphic infiltrate with absent or few foam cells and Touton giant cells. There is little inflammation, and mitotic figures are easily found. Four cases exhibit a diffuse sheetlike pattern while one is trabecular. Immunoperoxidase staining was done. All lesions are consistently positive for factor XIIIa as opposed to only focally positive or negative in CJXG and negative in Langerhans cell histiocytosis (LCH). The S-100 was negative. NJXG represents an atypical histologic variant of JXG, which may suggest a malignant or aggressive tumor. The follow-up, however, indicates that these lesions behave in a fashion similar to those of CJXG. The differential diagnosis should be made with LCH, intradermal nevus, and reticulohistiocytosis. The immunoperoxidase findings help to differentiate NJXG from these entities.
