Malignant proliferating tricholemmoma is a very rare dermatic annexal tumor originated from outer root sheath cells. In this article, a case of facial multiple malignant proliferating tricholemmoma was reported, and its clinical pathologic features, differential diagnosis, treatment methods and histogenesis were discussed by reviewing relevant literatures.

Basal cell carcinomas(BCCs) are the most common skin cancers in Korea and a proportion of BCCs contain pigment. Pigmented basal cell carcinomas(PBCCs) are included in the differential diagnosis of invasive melanoma and other benign pigmented skin lesions(PSLs) because of their growth patterns and asymmetry of pigmentation. Epiluminescence microscopy(ELM) describes the non-invasive in vivo examination of skin lesions with a microscope using incident light delivered from an acute angle and oil immersion. Many studies have shown that epiluminescence microscopy can improve the diagnostic accuracy of PSLs. Menzies et al analyzed the morphologic features of a large set of 142 pigmented BCCs and produced a simple ELM method for diagnosis that would allow differentiation from melanomas and benign pigmented lesions. We observed morphologic features of two PSLs with a handheld 10 epiluminescence microscopy (Episcope, Welch Allyn Inc, Skaneateles Falls, NY). After the ELM examination, two PSLs were excised and processed for histopathology. The ELM findings and histopathologic diagnosis were compared for each lesion. ELM permits the recognition of two PBCCs and the fact that it is a non-invasive in vivo method makes it even more attractive as a diagnostic tool in clinical practice.

BACKGROUND: Metastatic skin cancer may have profound diagnostic, therapeutic, and prognostic significance. OBJECTIVE: We studied patients with metastatic skin cancer to determine the relative frequencies of metastatic skin cancer according to the type and location of the primary tumor and the site of the cutaneous metastasis. METHODS: We reviewed medical records and histologic materials of 68 patients with metastatic skin cancer in Catholic University Hospital from January 1991 to March 2001. RESULTS AND CONCLUSIONS:Of 61,218 patients with internal malignancy, 68(0.11%) had metastatic skin cancer. The mean age at diagnosis was 64.7 in male and 58.2 in female. Male to female ratio was 1:2.2. Breast carcinoma was by far the most common primary neoplasm resulting in skin involvement and accounted for 31(45.6%) of total cases and 63.8% of the cases in women. The most common clinical presentation is a nodule(26.5%) or multiple nodules(64.7%) although carcinoma erysipelatoides(4.4%) and carcinoma en cuirasse(4.4%) were also seen. Histopathologic examination most frequently revealed adenocarcinoma(70.6%) that was sometimes suggestive of the site of origin.

Authors retrospectively analyzed ultrasonographic findings of 12 cases of breast carcinomas which were proven pathologically at Yeungnam University Hospital from March 1992 to August 1992. Classically, breast carcinomas were described as irregular and lobulated hypoechoic solid masses with inhomogeneous internal echoes and frequent attenuation of the sound beam. And other additional ultrasonographic findings were echogenic rim, disruptions of superficial layer, microcalcification, skin thickening and so on. In our studies, not all of these findings of breast carcinomas were found in each case, but most of these findings were noted. However, several studies have demonstrated considerable overlap in the ultrasonographic appearance of benign lesions and carcinoma. Thus, accurate sonographic determination of the type of solid mass is not possible with current ultrasonographic imaging techniques and criteria. For more accurate diagnosis of breast lesions, sonographic and other imaging techniques are interpreted together.
