Six cases of facial erythema with follicular plugging are described. These cases correspond with characteristics of the disorder pityriasis folliculorum, a presumed demodicidosis. Treatment modalities included topical tretinoin, gamma benzene hexachloride (lindane) lotion, and 1% permethrin cream rinse.
A patient known to have sarcoidosis exhibited cutaneous lesions. Microscopic examination of serial sections showed histologic evidence of transepithelial elimination of the sarcoidal granuloma. The concept and possible mechanisms of transepithelial elimination are discussed.
Ultrastructural features of the Medlar body, the tissue form of cutaneous chromomycosis, are reported. Striking variability in such features reflects the interaction between fungi and host defense mechanisms.
Botryomycosis is a chronic, granulomatous, bacterial infection in which grains are produced. Clinically, it may not be distinguished from a mycetoma of fungal origin. A case is reported in which the causative organisms were Staphylococcus aureus and Pseudomonas aeruginosa.
The common manifestation of pompholyx is easily recognized by the clinician. Morphologic variants are known in which the predominant lesions are pustules or desquamation with or without erythema. A patient is described herein whose eruption was composed mainly of arciform, annular, and target-like vesicles. Pompholyx (bubble) is a preferred term because "dyshidrosis" denotes a dysfunction of sweating, which does not occur in this condition. The causes of this eruption have not been determined, but it is likely that a certain genetic predisposition and multiple environmental factors are responsible. Pompholyx should be considered in the differential diagnosis of eruptions with annular pattern.
Presented herein is a report on a patient in whom a hyperkeratotic nodule developed in an abdominal surgical scar, ten months after exploratory laparotomy.
