Linear hypopigmentation and cutaneous atrophy following intra-articular steroid injections for de Quervain's tendonitis.

Intralesional and intra-articular corticosteroids are commonly used therapies in the fields of dermatology, orthopedic surgery and rheumatology. The authors present the case of a 32-year-old female who received intra-articular corticosteroids for de Quervain's tendonitis and developed bilateral hypopigmented patches near the areas of injection. Unilateral linear extension of the hypopigmentation was subsequently noted, presumably secondary to venous or lymphatic uptake of corticosteroid crystals.

ILVEN-like persistent psoriasiform dermatitis confined to a congenital Becker nevus.

A 10-year-old boy presented with a 5-year history of an intractably pruritic, recalcitrant psoriasiform plaque in a broad vertical band on the left buttock, with histologic as well as clinical features suggestive of an inflammatory linear verrucous epidermal nevus. This lesion was completely superimposed upon a congenital Becker nevus. We postulate that the restricted distribution and persistence of the psoriasiform plaque reflected an inflammatory response limited to the aberrant clone of cells composing the Becker nevus, a manifestation of cutaneous mosaicism that could be characterized as an "inflammatory Becker nevus.

Postradiation sarcoma: case report and review of the potential complications of therapeutic ionizing radiation.

Background: Radiation therapy is an acceptable treatment choice for many cutaneous malignancies. A potential late sequela of ionizing radiation is the development of secondary neoplasms within the treatment field. Although there are well-known cutaneous syndromes in which the use of ionizing radiation is contraindicated, in other clinical situations, physicians may not fully realize the risks associated with this therapeutic modality.

Precalcaneal congenital fibrolipomatous hamartomas: report of occurrence in half brothers.

Precalcaneal congenital fibrolipomatous hamartomas are uncommon, congenital, nontender papules located on the medial plantar aspects of the heel. We report the occurrence of this rare disorder in two half brothers, suggesting that it may occur in a familial pattern.

Hypertrophic herpes simplex virus in HIV patients.

In conclusion, HSV lesions in HIV patients can present as chronic, hyperproliferative plaques as opposed to the classic acute ulcerative lesions. Knowledge of this presentation will motivate the physician to be diligent in the diagnostic workup. This may necessitate repeat biopsies and cultures.
