Pilomatricoma or calcifying epithelioma of Malherbe is a benign tumor originating from the matrix of hair follicles. Clinically, these tumors are classified as familial, perforating, multinodular, exophytic, anetodermic, bullous, and giant pilomatricomas. The bullous variety is observed only in 3 to 6% of cases. Furthermore, multiple pilomatricomas are rare and are usually associated with genetic disorders. To date, only 13 cases of bullous pilomatricoma and 8 cases of multiple pilomatricomas have been reported in Korean dermatologic literature. Among these cases, no case of multiple bullous pilomatricomas has been reported. This report describes a 23-year-old healthy man who was diagnosed with multiple pilomatricomas with bullous features, based on clinical and histopathological findings.

BACKGROUND: Plasma cell cheilitis is an unusual benign plasma cell proliferative disease of an unknown etiology that typically presents on the lip. OBJECTIVE: The aim of this study was to investigate the clinicopathological characteristics of 13 cases of plasma cell cheilitis. METHODS: The present study investigated the clinical manifestations, treatment modalities, and outcome of 13 patients diagnosed with plasma cell cheilitis from 2011 to 2016 at Kangdong Sacred Heart Hospital and Hallym University Sacred Heart Hospital. Biopsy specimens of the all cases were evaluated using conventional hematoxylin and eosin staining with kappa and lambda immunoglobulin light chain immunohistochemistry. RESULTS: The age of the patients ranged from 39 to 86 years (mean, 64.7 years), with male predominance. Histopathologically, 61.5% and 38.5% of patients showed band-like and pan dermal plasmacytic infiltrates, respectively. Eosinophilic infiltration was noted in 69.2% of patients. All cases showed both kappa and lambda immunoglobulin light chain reactivities, and kappa predominance was confirmed in 9 patients (69.2%). A majority of the patients was treated with local therapy, such as intralesional steroid injection with topical tacrolimus. Among the 13 patients, plasma cell cheilitis completely resolved, partially resolved, and recurred in 3 (23.1%), 5 (38.5%), and 5 patients (38.5%), respectively. CONCLUSION: Plasma cell cheilitis presented as erosive edematous circumscribed patches or plaques affecting mainly the lower lip of elderly male patients. The majority of histopathology cases showed characteristic plasma cell aggregation on the upper dermis that was immunopositive for immunoglobulin light chain, with kappa predominance.
