We report the unique case of a 50-year-old African American female with pulmonary sarcoidosis who presented with a new ichthyosiform eruption symmetrically located on the anterior shins and surrounded by red, translucent, intradermal papules. A skin biopsy of a new red papule showed features consistent with granuloma annulare (GA) with positive mucin staining, and an older hyperpigmented papule showed classic dermal noncaseating granulomas consistent with sarcoidosis. ⋯ We propose that GA may act as a precursor lesion to the more mature sarcoidal granuloma. This case further underscores the importance of careful clinicopathologic correlation.

Herpes zoster is associated with depressed cell-mediated immunity and occurs rarely in the medically healthy nonimmunocompromised child. We report 4 cases of childhood-onset herpes zoster in the absence of a medical disorder. ⋯ It is possible that the severe chronic psychologic stress resulting from the abuse depressed the patients' cell-mediated immune status and thereby predisposed them to herpes zoster. Our findings suggest that the clinician's suspicion should be heightened for the possibility of covert child abuse and secondary stress when managing an otherwise apparently healthy child with herpes zoster.

Addison's disease is a potentially life-threatening endocrine disorder. The classic dermatologic sign of Addison's disease is diffuse hyperpigmentation of the skin with focal hyperpigmentation of scars, nails, and the oral mucosa. Recognition of these dermatologic manifestations in a patient with otherwise vague constitutional symptoms warrants a consideration of Addison's disease.

For centuries, scurvy, or vitamin C deficiency, decimated crews of sailing ships on long sea voyages and populations deprived of fresh fruits and vegetables during times of war or famine. Today, scurvy is extremely rare in the United States, and its classic findings of perifollicular petechiae, edema and purpura of the lower extremities, corkscrew hairs, and hemorrhagic gingivitis may go unrecognized. ⋯ Both times, the patient underwent an extensive work-up and was diagnosed with numerous other conditions before his vitamin C deficiency was recognized. We discuss the clinical presentation, pathophysiology, diagnosis, and treatment of scurvy, with attention to specific findings that should alert the clinician to this diagnosis.

Acute generalized exanthematous pustulosis is a rare but distinctive entity that may be associated with various etiologies. Drug exposure is the most common cause. We present the first report of acute generalized exanthematous pustulosis induced by the drug clindamycin.
