A patient with erythema gyratum repens in whom a bronchogenic carcinoma was found is described. Erythema gyratum repens is a cutaneous eruption with a unique morphology resembling a wood grain pattern. Its presence is almost always associated with serious systemic pathology, usually neoplastic, and thus should be considered a cutaneous marker of internal malignancy.
A case is reported of toxic psychosis in a patient with a diagnosis of discoid lupus erythematosus treated with hydroxychloroquine. The dose slightly exceeded the maximum recommended dose for 10 days because of a pharmacy error. Since more antimalarials are being used for various diseases, attention is called to this possible complication with a subtle onset.
Immunocompromised patients are more susceptible to unusual pathogens. The case of an immunocompromised patient who presented with cellulitis as the only manifestation of disseminated cryptococcosis is reported. The literature on cryptococcal cellulitis is reviewed.

As judged by passive hemagglutination and hemagglutination-inhibition assays, sera from six patients in one family with dominant epidermolysis bullosa contain clearly demonstrable titers of antibodies against the collagen C chain which is derived from basement membrane structures. Moreover, the circulating antibodies observed in these patients are apparently specific for the C chain as no titers were observed when using four additional well-characterized collagen chains in the indicated assays. In contrast to the results with sera from epidermolysis bullosa patients, sera from a series of age- and sex-matched healthy controls, as well as from a group of patients with bullous pemphigoid, did not contain antibodies to any of the test antigens. These results thus clearly differentiate the autoimmune response to basement membranes observed in bullous pemphigoid from that observed in epidermolysis bullosa simplex.
