Abstract
A 75-year-old woman presented with edema of the left leg in December 2012. On examination, there was a palpable 5-cm tumor in the left lower abdomen, and PET/CT showed lymphadenopathy of the tracheal, para-aortic, left iliac and inguinal regions with increased FDG uptake. We performed histopathological examination of the iliac lymph node and diagnosed diffuse large B-cell lymphoma (DLBCL), stage IIIA. The patient received 8 courses of R-CHOP chemotherapy and achieved a complete response. In April 2014, she noticed seven new painful erythematous vesicles <1 cm in size on the skin of the left lower abdominal region. Herpes zoster was suspected and valacyclovir was administered. However, this medication had no effect, and the vesicles enlarged and became nodular. Histopathological examination of one of the skin lesions revealed the infiltration of DLBCL and the diagnosis of zosteriform cutaneous recurrence of DLBCL was thus made. Skin lesions mimicking herpes zoster have been reported in certain types of hematological malignancies, and histopathological diagnosis should be performed in such cases.
