CASE REPORT A 73-year-old woman had a small nodule on the left upper lip for 8 months. She had insulin-dependent diabetes mellitus and CLL. Examination revealed a 0.8 cm, orange-red, translucent nodule. Shortly thereafter, a typical lesion of herpes simplex developed on the middle of her upper tip. One month later, a 6 cm nodule similar to the first lesion developed (Fig. 1). Biopsy specimens from each lesion revealed a diffuse, dense infiltration of the dermis by mature plasma cells (Fig. 2). Occasionally more atypical plasma ceils with binucleated forms were From the Unit of Dermatologya and Department of Pathology, b Hospital Universitario San Juan, Alicante, and the Department of Internal Medicine, Hospital Morales Meseguer, Murcia. c Reprint requests: Isabel Belinch6n, Avda Libertad 26 2-C, 03690 San Vicente, Alicante, Spain.

identified. Immunohistochemically, the plasma cells showed k fight-chain restriction. A routine blood examination showed a white blood cell count of 4.6 x 109/L (50% neutrophils, 45% lymphocytes, 5% monocytes, and no plasma cells), hemoglobin of 10.9 gm/L, erythrocyte sedimentation rate of 66 mrrd hr, glucose level of 10.6 mmol/L, and serum creatinine level of 132 pmol/L. Total protein was 75 gm/L with a serum albumin of 34 gin/L, alphaa 3 gm/L, alpha2 8 gm/L, and gamma 19 gm/L (slightly elevated). On serum immunoelectrophoresis a slight increase of IgG level was

al. 4 found a disease-related mortality rate o f at least 40%. Green et al. 3 described a patient in w h o m multiple primary cutaneous plasmocytomas developed after a possible insect bite reaction. Altcheck and Kurtin 7 described a patient with a cutaneous plasmocytoma on the cheek at the site o f a previous arthropod bite at the same site. Suster et al. 8 described a patient undergoing adjuvant immunotherapy with methanol extraction residue o f bacillus Calmette-Gu6rin for l y m p h o m a in w h o m a cutaneous plasma cell tumor developed at the injection site o f the drug. T o m e et al. 4 described a patient with a cutaneous lesion at the site o f previous herpes zoster, but no monoclonality was found in the plasma cells. In our patient her second lesion developed at the site of a previous herpes simplex infection. These cases m a y represent a polyclonal reaction from which a clone o f abnormal plasma cells develops. On the other hand, it is well known that there is an increase in frequency of solid neoplasms in patients with CLL. This could be explained by an immunologic deficiency in these patients or the carcinogenic effects o f chemotherapy. L6pez-Guillerm o et al. 9 in a review of 232 patients with C L L found that 13.8% had an associated neoplastic disease, but none had EMP. REFERENCES
observed (23.6 gm/L). Urinalysis, including a test for Bence-Jones protein, was negative. A skeletal survey disclosed no osteolyfic or osteoblastic changes. A bone marrow biopsy specimen showed 18% mature lymphocytic elements, without plasma cells. Immunologic studies showed 20% to 25% lymphocytes B, CD19 +, CD20 +, CD21-, CD25-, and CD10-. She received local radiotherapy with Iridio 192 (total dose, 48 Gy). The patient has remained flee of disease for 2.5 years since treatment. DISCUSSION
Wiltshaw 1 reviewed 272 cases o f E M P and found that it presents most c o m m o n l y in the upper aerodigestive tract. Primary cutaneous plasmocytoma without evidence o f marrow involvement is rare, accounting for only 3% to 12% o f cases. 1 The disease usually affects men in their 60s or 70s. 3-4 Previous reviews 2'3 5' 6' identified only about 30 cases o f primary cutaneous EMP, and a significant proportion o f the patients progressed to systemic disease.
