Subacute cutaneous lupus erythematosus in multiple members of a family with C2 deficiency.

Deficiency of the second component of complement (C2d) has been associated with systemic lupus erythematosus (LE)-like syndromes as well as recurrent infections. In particular, C2d has been associated with the LE subset of subacute cutaneous LE (SCLE), the presence of anti-Ro antibodies (anti-Ro or SS-A), and the human leukocyte antigen (HLA) types A25, B18, and DR2. A family with C2d in which three members have developed SCLE was observed and studied clinically, serologically, and immunogenetically. Deficiency of the second component of complement was present in all six family members, while anti-Ro was present in only two. There was a strong but incomplete association of C2d and SCLE with HLA-DR2, but the association was not complete with positivity of anti-Ro or antinuclear antibodies. Study of this family reconfirmed the close association of HLA-A25, -B18 and -DR2 with the C2 gene, but indicated a less close association of these loci with serologic markers.

The labial melanotic macule.

A series of 41 cases of melanotic lesions of the lip from 1980 to 1984 are reported. These lesions occur preponderantly in young white women on the lower lip. The term labial melanotic macule is suggested for these lesions.

Hyperkeratosis of the nipple and areola.

Hyperkeratosis of the nipple and areola is a rare condition. We report two cases of hyperkeratosis of the nipple and areola occurring in men with no underlying endocrinopathy or synthetic estrogenic drug therapy. Both patients demonstrated prompt resolution of the hyperkeratosis of the nipples with a keratolytic gel. Because our cases were not associated with ichthyosis or epidermal nevus, they best fit into the category of nevoid hyperkeratosis of the nipples.

Cutaneous non-X histiocytosis: clinical and histologic features and response to dermabrasion.

A 22-year-old man presented with a progressive cutaneous eruption consisting of reddish-yellow papules and plaques on his face, which was histopathologically characteristic of a non-X histiocytosis. No systemic involvement was present. Monoclonal antibody staining of the tissue infiltrate was strongly positive for only OKT6. On electron microscopy, Langerhans (Birbeck) granules were not found. Four years of conservative treatment was unsuccessful. Spontaneous involution did not occur. Dermabrasion not only produced excellent cosmetic results, but on rebiopsy the histiocytic infiltrate was absent. There has been no recurrence in treated areas after 18 months.

Linear eccrine nevus with comedones.

We report herein a case of a linear nevus comedonicus associated with tumors of sweat gland origin. We propose the term "linear eccrine nevus with comedones" as a suitable title for this disorder. Several similar cases in the literature are reviewed.

Transfusion therapy in a patient with erythropoietic protoporphyria.

An 8-year-old boy with erythropoietic protoporphyria had a marked decrease in photosensitivity symptoms after several transfusions with washed, packed RBCs. The reduction in photosensitivity was associated with a decline in free erythrocyte protoporphyrin levels.

Blood Transfusion↗

Eczematous dermatitis caused by Dermanyssus americanus.

A patient is presented herein with an acute generalized eczematoid eruption. The onset occurred in late spring and was caused by the American bird mite, Dermanyssus americanus. A review of mite infestations is presented. We suggest that puzzling cutaneous eruptions be evaluated closely as being possibly caused by mites.

Cutaneous horns: a histopathologic study.

We report a series of 230 cutaneous horns, of which fewer than one fourth were frankly malignant. Actinic keratoses were the lesions most commonly found underlying cutaneous horns (37.39%). Cutaneous horns overlying a benign lichenoid keratosis, epidermolytic hyperkeratosis, trichilemmoma, an epidermal inclusion cyst, and a benign fibroma are reported. Three cases were nondiagnosable because of inadequate biopsies that were too superficial to show the base of the lesion.

Carcinoma, Squamous Cell↗

Zosteriform inflammatory metastatic carcinoma.

A 57-year-old man presented with chest wall lesions and swelling of his left arm. The rapid onset of vesicular lesions in a dermatomal distribution resulted in an initial diagnosis of herpes zoster. Cutaneous biopsy revealed adenocarcinoma and further evaluation revealed a primary source of pulmonary adenocarcinoma. Lymphatic spread of tumor cells is the most likely source of the zosteriform skin lesions, but other possibilities are discussed.

Adenocarcinoma↗

Cutaneous angiosarcoma of the hip.

An elderly patient is presented who developed a fatal angiosarcoma of the hip about ten years after surgery and radiation for a uterine malignancy. She developed a metastasis of the uterine tumor, requiring additional radiation, which led to aseptic necrosis of the hip and chronic joint and soft tissue infection of the hip from a joint prosthesis. Subsequently she developed chronic lymphedema of the hip and finally the cutaneous angiosarcoma in this area. Any or all of these factors might bear a causative relationship to the angiosarcoma, but none can be proved.
