Pilomatricoma is a relatively rare tumor of the skin derived from primitive basal cells epidermis that differentiate into hair matrix cells. These tumors appear as solitary, firm nodules, showing normal to pearl white epidermis. Its most frequent locations are head and neck, while involvement upper extremities uncommon. Herein, we present case seventeen-year-old female with pilomatricoma arm re...

Pilomatricoma is benign skin adnexal tumour arising from the hair follicle matrix. Its most common location is maxillofacial region followed by upper extremities. Lower extremities are a rare site for this tumour. It presents as a skin nodule and rarely exceeds 5 cm in diameter. We are thus presenting an unusual case of pilomatricoma on thigh of a young male which was clinically thought to be a...

This is a report of papillary endothelial hyperplasia in a 9-year-old girl with a pilomatricoma showing bullous appearance. Histologically, papillary proliferation of endothelial cells was found within dilated lymphatic endothelium-lined vascular channels overlying a pilomatricoma. The endothelial cells covering the papillae were of a lymphatic endothelial cell nature proved by immunohistochemi...

Proliferating pilomatricoma is proliferative, rare tumor variant of pilomatricoma. It is a benign neoplasm of hair matrix that can have potentially involve local recurrence. We report the case of a 60-year-old man who presented an asymptomatic nodule on the scalp. Histological exam demonstrated a basaloid epithelium at the periphery, filled with eosinophilic cornified material containing shadow...

730 To the Editor: Pilomatricoma is a benign neoplasm that is generally straightforward to diagnose clinically. It initially takes the form of a small tumor of nonspecific appearance but displays a characteristic firm consistency to palpation as it develops. We present the case of a giant pilomatricoma on the scalp, noting the abnormal morphology and rapid growth. We also describe a surgical so...

Pilomatricoma is a relatively common benign skin neoplasm originating from the hair follicle matrix cells. β-Catenin is a subunit of the cadherin protein complex. It acts as an intracellular signal transducer that influences cell differentiation and proliferation. This protein was recently involved in the formation of hair follicle-related tumours, including pilomatricomas. Tuberous sclerosis (...

Abstract Pilomatricoma, pilomatrixoma, or calcified epithelioma of Malherbe is an uncommon, benign, isolated tumor hair matrix primarily seen in children and young adults. The most common location the head neck region. It usually manifests as a small nodular mass. Here we report rare case giant pilomatricoma over sternum 60-year-old male patient with unusual clinical radiological presentation m...

Malignant pilomatricoma is malignant follicular tumor with only matrical differentiation. Malignant pilomatricoma is rare in dogs. There is little information about sex, breed and age predisposition. There are a few reports of canine malignant pilomatricoma in middle to old age dogs. However, this neoplasm was resected from 1-year-old intact male miniature poodle. The neoplasm was found in the ...
