Lichen scrofulosorum.

A 12-month-old boy with pulmonary tuberculosis developed a papular lichenoid eruption which showed epithelioid granulomas on histology, consistent with lichen scrofulosorum. Stains and cultures for mycobacteria in the skin were negative, and a polymerase chain reaction (PCR) analysis failed to detect the DNA of Mycobacterium tuberculosis in a skin biopsy specimen, thus making lichen scrofulosorum one of the remaining manifestations of M. tuberculosis infection in which evidence of the bacillus has not been found to date. Lichen scrofulosorum is now considered a rare form of tuberculid but should not be neglected.

A cutaneous eruption from G-CSF in a healthy donor.

A healthy 12-month-old donor treated with G-CSF for collection of stem cells from peripheral blood developed a discrete, papular, erythematous eruption which histologically showed irregularly shaped lymphocytes with mitoses. We suggest that such a reaction is due to activation of lymphocytes by G-CSF in a normal host, leading to atypical changes in cellularity.

Primary cutaneous Mycobacterium kansasii infection in a child.

A 6-year-old girl with a primary cutaneous form of Mycobacterium kansasii infection is presented. Disseminated infection and immune deficiency were excluded in our patient. She was successfully treated with surgical excision and oral erythromycin. Primary cutaneous M. kansasii is an exceedingly rare infection in children.
