Localized Sweet's Syndrome in an Irradiated Field.

Sweet's syndrome is a reactive dermatosis characterized clinically by fever, leukocytosis, and multiple, erythematous, painful plaques. Histopathologic examination reveals a band-like dense dermal inflammatory infiltrate composed mainly of neutrophils with papillary dermal edema, and no features of vasculitis. We report a case of a 56-year-old female diagnosed with cervical cancer, who underwent surgery and concurrent chemoradiation therapy.

A Case of Acantholytic Squamous Cell Carcinoma.

Acantholytic squamous cell carcinoma is a well-defined variant of squamous cell cancer in which significant portions of the neoplastic proliferation show a pseudoglandular or tubular microscopic pattern. It usually presents as a nodule with various colors, and it is accompanied by scaling, crusting, and ulceration on the sun-exposed areas of older aged individuals. Histologically, the tumor consists of a nodular, epidermal-derived proliferation that forms island-like structures.

Pseudoxanthoma elasticum-like papillary dermal elastolysis developed in early middle age.

Pseudoxanthoma elasticum-like papillary dermal elastolysis is a rare acquired elastolytic disorder characterized by papules that resemble pseudoxanthoma elasticum, and it typically affects elderly women. Histopathological examination shows atrophic epidermis and band-like loss of elastic tissue in the papillary dermis. The pathogenesis is assumed to be related to intrinsic aging because it affects elderly people and shows the loss of elastic tissue.

Generalized lichen nitidus successfully treated with narrow-band UVB phototherapy: two cases report.

Lichen nitidus (LN) is an uncommon chronic inflammatory skin disease composed of numerous, tiny, shiny, flesh-colored papules that are predominantly observed on the chest, abdomen, glans penis and upper extremities. The distribution of LN is most often localized, but in some cases it can become generalized. Because LN tends to be asymptomatic and presents spontaneous resolution within several years, it usually does not require treatment except in symptomatic, persistent and generalized cases.
