Although nevus sebaceus is known to develop various types of secondary neoplasms, it rarely causes carcinoma and only 14 cases of secondary sebaceous carcinoma have been reported. In this study, 10 cases of sebaceous carcinoma arising in nevus sebaceus were collected. The clinicopathological features and results of immunohistochemical examinations with adipophilin, perilipin and p53 were summarized. Sebaceous carcinoma arising in nevus sebaceous predominantly occurred on the scalp (8/10) of elderly women (mean age, 67.7 years). No case was associated with Muir–Torre syndrome. We found several pathological features of sebaceous carcinoma; that is, made up mainly of germinative cells, moderate nuclear atypia without pleomorphism and many mitoses (4–28/10 high‐power field). Adipophilin and perilipin antibodies highlighted lipid drops in the cytoplasm of the malignant cells in all cases. Overexpression of p53 was seen in all cases. In two cases there were coexisting benign‐looking sebaceous lesions at the periphery of the main cancer nodule, and in these lesions p53 showed low positivity compared with the clearly malignant area. There was co‐occurrence of another neoplasm in three cases with trichoblastoma, sebaceoma and syringocystadenoma papilliferum, respectively. All cases were treated by excision of the malignant lesion, with or without inclusion of the nevus sebaceus. In a follow‐up period of 1–7 years, there was no case of recurrence, lymph node metastases or distant metastases. With these specific pathological and immunohistochemical findings using adipophilin, perilipin and p53, we have to consider the possibility that there is a tendency to underdiagnose secondary sebaceous carcinomas in nevus sebaceus. These clinicopathological features of sebaceous carcinomas developing in the nevus sebaceus seem to indicate different biological entities from de novo sebaceous carcinoma. 相似文献

A 53-year-old woman had had a pale-brown lesion on her right cheek and neck from birth. Since she was about 40 years old, part of the lesion had gradually elevated and increased in size. At the first examination, there was a huge mass measuring 110 x 70 x 35 mm on the right cheek. A wide local excision of the area including a superficial parotidectomy and submandibular lymph node dissection was performed, followed by full thickness skin grafting. Histological examination of the tumor revealed an invasive dermal neoplasm characterized by lobes that were composed of foamy cells stained with Sudan-IV mixed with many atypical cells showing remarkable variation in the shapes and sizes of their nuclei. The surrounding epithelial changes were consistent with nevus sebaceus. From these findings, the gigantic tumor was diagnosed as a sebaceous carcinoma arising in nevus sebaceus. 相似文献

Nevus sebaceus is frequently associated with the development of secondary neoplasms. Incidences of malignant transformation vary among different reports and few data is available regarding Asian populations. We aimed to determine the characteristics of secondary tumors developing from nevus sebaceus in a Taiwanese population and to review the published work. Patients with clinically and histologically confirmed nevus sebaceus were identified from 1992 to 2012 in a medical center. Among the 450 cases of nevus sebaceus, 38 secondary neoplasms were noted, accounting for 8.5% of all cases. Benign tumors represented more than 80% of all tumors. Syringocystadenoma papilliferum (2.7%) was the most common benign tumor, followed by trichoblastoma (1.6%) and trichilemmoma (1.6%) whereas basal cell carcinoma (0.9%) was the most frequent malignant tumor on nevus sebaceus and its clinical features were not typical. All the malignant tumors on nevus sebaceus were noted only in adulthood and the mean age of those with basal cell carcinoma was significantly older than that of trichoblastoma (P = 0.028). Our study concludes that malignant transformation is rare in nevus sebaceus and occurs uniquely in adulthood. On the basis of the findings, prophylactic excision of nevus sebaceus can be elective during childhood but is strongly advocated at puberty due to the increased risk of malignant transformation with time. 相似文献

Background: Nevus sebaceus (NS) is a congenital hamartomatous lesion, usually involving the scalp or the face. Various benign and malignant neoplasms can develop in association with NS, the most common being trichoblastoma, syringocystadenoma papilliferum, viral warts and basal cell carcinoma (BCC). Patients and methods: We retrospectively examined the clinical and histopa‐thological records of 15 NS cases with an associated tumor which were diagnosed between 1996 and 2004. Results: All cases were adults and 3 of them had more than one tumor. Six cases had BCC, which is a higher incidence of malignant tumor association with NS, than that reported in last years. Trichoblastoma was observed in 3 cases and was the most common benign tumor in our series. Filiform, hyperkeratotic, pigmented, pedunculated and/or eroded papulonodular changes were major clinical signs of secondary tumors on NS in our series. Conclusion: Clinical features are not sufficient enough to make an exact diagnosis of benign or malignant secondary tumors. Though prophylactic excision for NS is done less in last years, especially adult patients should closely be followed for any new changes evoking tumor development on this congenital lesion. 相似文献

Basal cell carcinoma is the most common tumor in Central Europe, the U.S. and Australia. The increasing incidence of basal cell carcinoma presents the health care system, especially dermatology, with great challenges. In recent years new options for treating basal cell carcinoma have become available, enriching our therapeutic options. We review the current status of each of these treatment approaches. 相似文献

We report a case of sarcomatoid carcinoma of the skin in a 63‐year‐old man who was treated with the carbon dioxide snow freezing method for a huge congenital pigmented nevus that extended from the right upper extremity to the right trunk during childhood. He had an exophytic red tumor on the nevus in the right upper extremity that grew slowly for 4 years and rapidly recently. Histological and immunohistochemical studies revealed both epithelial and mesenchymal malignancy in the same tumor. The epithelial component was composed of basaloid cells forming multiple nests with peripheral palisading, positive for keratins and BerEP4, implying basal cell carcinoma. The mesenchymal component was composed of spindle‐shaped cells negative for keratins and positive for vimentin, suggesting sarcoma. This is, to our knowledge, the first report of sarcomatoid carcinoma arising in the primary pigmented nevus that had been treated by the carbon dioxide snow freezing method. 相似文献

Basal cell nevus syndrome (BCNS), also known as Gorlin syndrome, is characterized by an aberrant activation of the hedgehog (Hh) pathway, most cases being caused by PTCH1 mutations. However, certain features such as multiple hereditary infundibulocystic basal cell carcinomas (MHIBCC), sclerotic fibromas, childhood medulloblastoma or meningioma may be relatively specific to a SUFU mutation. We present two patients with MHIBCC, along with a more complex cutaneous and extracutaneous phenotype. MHIBCC syndrome and BCNS may share clinical features and, indeed, both syndromes probably represent different degrees of upregulation in the Hh pathway. 相似文献

A 29‐year‐old man visited our department with an orange‐colored patch on his right cheek. A skin biopsy confirmed the diagnosis of nevus sebaceous. As surgical excision was considered too destructive, photodynamic therapy (PDT) was proposed. Sixteen sessions of PDT was performed in total. There was a definitive but transient decrease in sebum production and destruction of the sebaceous glands. Overall, we were not able to achieve long‐lasting clinical improvement after PDT. 相似文献
