PURPOSE The purpose of this study was to describe the clinical and sonographic features of calcifying epitheliomas (pilomatrixomas). METHODS We retrospectively reviewed the clinical data and sonographic appearances of 59 cases of calcifying epitheliomas in 58 patients that were confirmed pathologically. RESULTS The mean age of the patients was 26 years (range, 5-69 years) and the female-to-...

Pilomatrix carcinoma is a skin tumour about which there is a relative paucity of material in the plastic surgical literature. In the course of their practice most plastic surgeons will have come across the benign skin lesion designated "Clacifying Epithelioma o Malherbe" named thus in recognition of Malherbe\'s description of the entity in I 880, even though erroneously ascribed the tissue of o...

<p class="abstract">Malignant pilomatrixoma is a rare malignancy with just 136 cases reported in the English literature. The tumour described as locally aggressive, possibility of reoccurrence and distal metastasis. Histology remains gold standard diagnostic. Wide surgical excision preferred to simple excision. In present study case first malignant our hospital described. We made an tissu...

OBJECTIVES To determine the effectiveness of interventions designed to prevent or reduce publication and related biases. STUDY DESIGN AND SETTING We searched multiple databases and performed manual searches using terms related to publication bias and known interventions against publication bias.

Proton transfer reaction-mass spectrometry (PTR-MS) is a spectrometric technique that allows direct injection and analysis of mixtures of volatile compounds. Its coupling with data mining techniques provides a reliable and fast method for the automatic characterization of agroindustrial p w d t d c ©

Pilomatricoma is a benign cutaneous tumor originatingfrom hair matrix cells. Anetodermic changes inthe skin overlying pilomatricomas are sometimesreported, although their precise mechanisms remainunknown. We present an unusual case of anetodermicpilomatricoma on the upper extremity of a 17-yearoldboy and report its clinical, histopathologic, andsonographic findings.

Pilomatricomas are relatively rare tumors of ectodermal origin from the outer root sheath cell of the hair follicle. They are usually asymptomatic, solitary, firm or hard, freely mobile, dermal or subcutaneous nodules. The purpose of this article is to present a case that illustrates the diagnostic difficulty encountered by oral surgeons and pathologists and to review the literature regarding p...
