Multiple fibroepithelial basal cell carcinoma of Pinkus associated with seborrheic keratosis in a nevoid distribution

We describe a patient with multiple fibroepithelial basal-cell carcinoma (FEBCC) associated with seborrheic keratosis distributed in a neviform fashion on the left side of the body and clinically resembling skin tags.     

Case of seborrheic keratosis with underlying basal cell carcinoma suggesting a collision tumor

Reports of seborrheic keratosis (SK) with concurrent malignant tumors are rare, but previous and recent reports – especially the co‐manifestation of basal cell carcinomas (BCC) have added to the ongoing debate of the possibility of the development of BCC from SK. We report a rare case of SK with underlying BCC with scarcely accounted histopathological characteristics – reticulated type and nodular type, respectively – that showed no direct histological link between the two entities. We also carefully suggest that differences in histopathology (whether the two lesions are connected or not) may account for the possibility of incidental co‐habitation.     

A case of cutaneous ganglioneuroma developing within a lesion of seborrheic keratosis

A 67-year-old man noticed on the abdominal skin a coin-sized verrucous plaque, in which a small granulation-like lesion developed several weeks before the first consultation at our clinic. The histology of the biopsied granulation-like lesion showed a well demarcated, but not associated with the collagenous capsule, mass of proliferating eosinophilic cells, consisting of intervening spindle-shaped Schwann cells and mature ganglion cells scattered in the tumor nest. We diagnosed this tumor nest as a ganglioneuroma, which rarely develops in the skin tissue. The simply resected surrounding verrucous lesion was histologically seborrheic keratosis.     

Image analysis for quantification of nucleolar organizer regions in basal cell carcinoma and seborrheic keratosis

Background/aims: Nucleolar organizer regions (NORs) have recently attracted much attention because of claims that their frequency within nuclei is significantly higher in malignant cells than in normal, reactive, or benign neoplastic cells. The purpose of this paper is to analyze a method allowing selection of the best morphometric criterion for quantifying AgNORs (Silver stained Nucleolar organizer Regions) under conventional observation conditions, by light microscopy.
Methods: The various parameters including NORs counting in cutaneous tumors using image analysis system were studied.
Results: There were significant differences in mean numbers of AgNORs per nucleus, mean ratio of AgNORs area per nucleus area, mean ratio of greatest AgNORs area per nucleus area, mean nucleus area per a AgNOR, and CV (Coefficient of Variation) of AgNORs area between basal cell carcinoma and seborrheic keratosis.
Conclusion: Study of AgNORs using the image analysis system is a useful tool for diagnosis of cutaneous tumors.     

埃兹蛋白在皮肤鳞状细胞癌、基底细胞上皮瘤、脂溢性角化病中的表达及临床意义

目的 探讨埃兹蛋白（ezrin）在脂溢性角化病、基底细胞上皮瘤、皮肤鳞状细胞癌中的表达及其与临床病理参数之间的相关性。方法 采用免疫组化法（SP法）检测36例皮肤鳞状细胞癌、27例基底细胞上皮瘤和20例脂溢性角化病、10例正常人皮肤中埃兹蛋白表达水平。结果 埃兹蛋白在正常人皮肤、脂溢性角化病、基底细胞上皮瘤、皮肤鳞状细胞癌中的阳性率分别为20.0%,25.0%,66.7％和91.3%,除脂溢性角化病组外,各肿瘤组与正常人对照组比较,阳性率差异均有统计学意义（H = 40.061,P < 0.01）。埃兹蛋白表达水平与皮肤肿瘤良恶性、与皮肤鳞状细胞癌的病理分级及肿瘤有无淋巴结转移均呈正相关（r分别为0.87,0.80,0.89）。COX回归显示,埃兹蛋白表达水平是皮肤鳞状细胞癌预后的独立影响因素之一。结论 脂溢性角化病、基底细胞上皮瘤、皮肤鳞状细胞癌组织中埃兹蛋白阳性表达水平与皮肤肿瘤的良恶性、皮肤鳞状细胞癌病理分级及有无淋巴结转移有关。     

Pedunculated basal cell epithelioma which is not Pinkus tumor

A 33-year-old female with pedunculated basal cell epithelioma was reported. She had noticed a cutaneous tumor on the scalp for two years before admission.
