RESUMO
OBJECTIVE: Two cases of varicella-zoster virus infection that were clinically and pathologically verrucous are reported. Although this phenomenon has previously been described in the dermatology literature, it has not, to our knowledge, been described in the pathology literature. It is important that pathologists are aware of these uncommon but histologically distinctive lesions. DATA SOURCES: The patients were seen and treated at the Departments of Dermatology of the University of Texas Health Science Center at San Antonio and Brackenridge Hospital in Austin, Tex. All information was derived from the medical records and from the attending physicians. CONCLUSIONS: Verrucous lesions of herpes (varicella) zoster virus infection are rare, but they do occur in patients with the acquired immunodeficiency syndrome. Clinically, the lesions studied resembled ordinary papillomavirus-induced verrucae. Histologically, there was verrucoid epidermal hyperplasia and, unlike ordinary lesions of herpes (varicella) zoster, very little inflammation of the dermis. Diagnostic multinucleated keratinocytes with herpesvirus cytopathic changes were present within the stratum corneum.

Bacillary angiomatosis (BA), an infection caused by a gram-negative rod, can be a multiorgan disease. The usual causative organism, Bartonella (formerly Rochalimaea) hensalae, has only recently been identified. Bartonella quintana has also been shown to cause some cases of cutaneous BA. We describe a patient with widespread cutaneous BA with probable bone involvement and a large fungating mass.

BACKGROUND: Chronic myelomonocytic leukemia has been associated with various nonspecific cutaneous manifestations. Rarely has the leukemia been reported to directly affect the skin. METHODS: This case documents the progression of a patient who ultimately developed chronic myelomonocytic leukemia, by clinical examination, hematologic parameters, dermatopathology, and bone marrow pathology. RESULTS: The skin showed nonspecific cutaneous involvement, progressing to specific leukemic lesions parallel with increasing systemic and hematologic involvement. CONCLUSIONS: Chronic myelomonocytic leukemia can manifest with lesions of leukemia cutis. The possibility of nonspecific cutaneous involvement in the preleukemic phase exists.
