Early-onset acral basal cell carcinomas in Gorlin syndrome.

Two patients are reported in whom early-onset, distal papules with a histopathological diagnosis of basal cell carcinoma were the first manifestation of Gorlin syndrome (GS). These lesions showed no progression and remained stable through follow-up. Two different PTCH1 gene mutations were detected in the two patients, and thus a phenotype-genotype correlation of this manifestation of GS was not possible.

Primary cutaneous B-cell lymphoma (marginal zone) with prominent T-cell component and aberrant dual (T and B) genotype; diagnostic usefulness of laser-capture microdissection.

The presence of a dominant B- or T-cell clone is an important diagnostic criterion for distinguishing cutaneous lymphomas from lymphoid reactive infiltrates. Rarely, a combined B- and T-cell rearrangement can be detected from a single sample. In such instances, genotypic analysis does not permit differentiation of the coexistence of a T- and B-cell lymphoma from a single clone harbouring a monoclonal rearrangement for both immunoglobulin heavy chain and T-cell receptor genes.

Anetoderma associated with antiphospholipid antibodies: case report and review of the literature.

The association of primary anetoderma (PA) with antiphospholipid antibodies (APAs; with or without criteria of primary antiphospholipid syndrome) has been observed repeatedly and a possible pathogenic significance of this asssociation has been hypothesized. We report the case of a 21-year-old-woman who developed anetodermic lesions on her upper trunk and arms. The presence of APAs was demonstrated, but no diagnostic criteria of systemic lupus erythematosus were present.

Clinical, histopathologic, and therapeutic aspects of subepidermal autoimmune bullous diseases with IgG on the floor of salt-split skin.

Background: About 12% of patients with subepidermal autoimmune bullous disease and immunoglobulin G (IgG) at the dermal-epidermal junction present diseases other than bullous pemphigoid.

Materials And Methods: We report the clinical, histopathologic, and therapeutic aspects of eight cases of subepidermal bullous disorder with IgG on the floor of salt-split skin.

Results: A predominant neutrophilic infiltrate was detected in six of the eight patients.

Focal dermal hypoplasia (Goltz syndrome): report of two cases with minor cutaneous and extracutaneous manifestations.

Two women, ages 33 and 16 years, had focal dermal hypoplasia (Goltz syndrome) with unusual, minimal clinical manifestations. The lesions consisted of patchy, atrophic, scaly, telangiectatic macules arranged in a linear pattern along Blaschko's lines, involving the anterior and lateral aspects of both legs (patient 1) and the anterolateral aspect of the left leg (patient 2). Type I partial syndactyly involving the second and the third toes in both patients was also present.
