Hair-bearing, transitional, and alopecic scalp from three males and one female with progressive pattern alopecia were examined. Ultrastructural studies disclosed measurable thickening of the follicular adventitial sheaths of transitional and alopecic zones compared with those in the non-alopecic zones. This finding was associated with mast cell(More)
We have previously demonstrated that peripheral blood mononuclear cells from patients with Sézary syndrome, the leukemic form of cutaneous T-cell lymphoma which is accompanied by erythroderma and lymphadenopathy, have a Th2 cell cytokine [interleukin 4 (IL-4) and interleukin 5] production pattern. In this study, we extend these observations to demonstrate a(More)
OBJECTIVE To determine if changes in histologic parameters obtained from intermittent sampling of the entire block correlated with differences in prognosis and management. DESIGN Prospective analysis of skin biopsy specimens. SETTING Skin pathology laboratory. Patients One hundred consecutive patients with an unequivocal diagnosis of melanoma.(More)
The neu (c-erbB-2) gene encodes a transmembrane protein with tyrosine kinase activity that appears to be a growth factor receptor. Antibody was generated by immunization of rabbits with a synthetic polypeptide that was based on an internal sequence at the carboxy terminus of the molecule. This antibody was used to survey the expression of neu in human skin(More)
A 91-year-old female presented with widespread skin sloughing and bullae clinically mimicking toxic epidermal necrolysis (TEN). The patient was on multiple antibiotics, including vancomycin and piperacillin/tazobactam. Histopathology and direct immunofluorescence were consistent with a diagnosis of linear IgA bullous disease (LABD). In a PubMed review of(More)
Benign cephalic histiocytosis is a rare non-Langerhans histiocytosis characterized by a self-healing eruption of papules and macules on the head and neck that occurs during infancy or childhood. Histologic and ultrastructural evaluations show a dermal proliferation of histiocytes with intracytoplasmic comma-shaped bodies, coated vesicles, and desmosome-like(More)
BACKGROUND Seborrheic keratoses have on rare occasion been reported to undergo malignant transformation. OBJECTIVE Our purpose was to examine the incidence and distribution of squamous cell carcinomas (SCCs) in situ arising in clinically banal-appearing seborrheic keratoses. METHODS We prospectively selected such cases over a 6-month period of time from(More)
Cryopreserved cell suspensions of freshly excised melanoma metastases from nine patients were injected s.c. into C.B-17 severe combined immunodeficiency (SCID) mice. All 9 tumors grew as s.c. masses and six of nine were successfully transplanted into other SCID mice. Transplant inocula as low as 5 x 10(5) cells resulted in 100% tumor incidence. Moreover,(More)
Sorafenib is a multikinase inhibitor newly approved for the treatment of renal cell carcinoma and hepatocellular carcinoma. Multiple cutaneous adverse effects of sorafenib have been described. We present a 68-year-old patient with renal cell carcinoma who developed multiple tender hyperkeratotic papules within weeks of starting sorafenib. The degree of(More)
A healthy 58-year-old woman developed an asymptomatic papular eruption of the neck, cheek, abdomen, arms, and flexures. There was an 8-year history of the lesions, which had erupted when the patient started a strict vegetarian diet. Lesions lasted 3 to 5 days, cleared without scarring, and were associated with burning and increased tearing of the eyes. The(More)
