We report a case of a 10 year-old girl diagnosed with sebaceous carcinoma of the posterior left arm. The presented case reviews the histopathological and immunohistochemical characteristics of this malignancy, including a review of the literature in pediatric patients regarding prognosis and treatment. Sebaceous carcinoma is a malignant neoplasm with sebaceous differentiation, typically occurring in the sixth-to-seventh decades of life. It most commonly arises in the periocular region. It is extremely rare in the pediatric population...

Sebaceous carcinomas are rare but potentially fatal malignant adenocarcinomas with varying degrees of sebaceous differentiation. Several dermoscopic findings of extraocular sebaceous carcinomas have been reported; however, there are no previous reports of ocular sebaceous carcinomas detected using dermoscopy. We present a case of ocular sebaceous carcinomas showing specific findings from dermoscopy, and describe the common dermoscopic characteristics. In our cases and a review of cases in the literature, we noted that polymorphous vessels and yellowish areas were observed in all eight cases...

BACKGROUND: A variety of genodermatoses with multiple cutaneous tumors with germline genetic alterations such as Gorlin syndrome with PTCH1 gene mutations have been described. Other cutaneous syndromes have been associated with somatic gene mutations, such as FGFR3 in familial seborrhoeic keratosis. OBJECTIVE: We describe the clinical, dermoscopic, and histopathological features of multiple cutaneous lesions, mostly infundibulocystic basal cell carcinomas and pure reticulated acanthomas, present in a family affected by familial seborrhoeic keratosis...

Skin cancer incidence rates are continuing to rise; however, if detected at an early stage, they can be cured with minimally invasive treatment. Therefore, the identification of novel and robust biomarkers for the early detection of skin cancer is required to improve the quality of life of the patient after treatment. In the present study, we aimed to identify novel biomarkers of skin cancers. We carried out serum metabolomics using gas chromatography/triple quadrupole mass spectrometry for two types of skin cancer: squamous cell carcinoma and melanoma...

Basal cell carcinomas (BCC) are the most frequent tumours in humans and normally appear in photoexposed areas of the skin. It is widely accepted that BCCs originate at follicular stem cells and consequently are very rare in nonhairy areas. Here, we report 4 cases of vulvar BCC, 3 of which were located in a vulvar semimucous area, a nonphotoexposed area, and a nonhairy area. We have determined the CK7 and CK19 profile of all cases; both are markers of simple epithelium with glandular differentiation. Interestingly, all cases were positively stained for CK7 and CK19...

Sebaceous carcinoma (SC) represents a rare, aggressive eyelid malignancy with poor prognosis and is a possible component of Muir-Torre syndrome. However, genetic features as driver mutations or potential therapeutic targets are not fully elucidated. Recent a few studies have shown that SCs have concurrently multiple mutations including RAS/RAF/MAPK and PI3K/Akt pathways via next-generation sequencing in western population. Because we recently demonstrated absence of KRAS mutations in Korean eyelid SCs, we extended our previous study to the analysis of NRAS, BRAF, PIK3CA, and CTNNB1 mutations, and the examination of related protein expressions in 15 eyelid SCs...

Basal cell carcinoma (BCC) is the prototypical basaloid tumor of the skin. It may show various patterns simulating other cutaneous tumors due to its pleomorphism. It may have an unusal pattern of differentiation such as squamous, sebaceous, apocrine, eccrine, pilar, and endocrine differentiation. In order to establish the relative frequency of neuroendocrine differentiation in BCC, we performed a retrospective study of 33 consecutive BCCs using conventional immunohistochemistry with two neuroendocrine antibodies: Chromogranine A and synaptophysine...

BACKGROUND: Muir-Torre syndrome (MTS) is a rare autosomal dominant genodermatosis caused by mutations in mismatch repair genes. It is characterized by the presence of at least one sebaceous skin tumor associated with internal malignancies. Whether positron emission tomography/computed tomography (PET/CT) is useful for the detection of malignancies in patients with MTS has not been determined. We herein report two cases in which PET/CT was useful for the diagnosis and follow-up of internal malignancies in patients with MTS...

Lymphocytic infiltrations located in the extracellular matrix often accompany canine skin cancer. They can be characterised as an inflammatory infiltration and/or a second tumour - lymphoma. The aim of this study was an immunohistochemical analysis of a lymphocytic infiltration which accompanies spontaneous skin cancer. Twenty basal cell carcinoma, 20 non-keratinizing squamous cell carcinoma, 20 keratinizing squamous cell carcinoma and 8 sebaceous gland carcinoma samples which were accompanied by a lymphocytic infiltration and/or secondary lymphatic follicles were verified histopathologically...

BACKGROUND: The tumor spectrum in the Lynch syndrome is well defined, comprising an increased risk of developing colonic and extracolonic malignancies. Muir-Torre syndrome is a variant with a higher risk of skin disease. Patients have been described carrying mutations in the mismatch repair genes and presenting tumors with unusual histology or affected organ not part of the Lynch syndrome spectrum. Hence, the real link between Lynch syndrome, or Muir-Torre syndrome, and these tumors remains difficult to assess...

Eyelid malignancies represent between 5% and 10% of all skin cancers. Basal cell carcinoma is the most common, followed by squamous cell carcinoma, sebaceous cell carcinoma, Merkel cell carcinoma, and melanoma. The gold standard treatment for periocular epithelial malignancies is surgical excision. Given the constraints of the anatomy and function of the eyelids, excision with negative margins and reconstruction can be challenging. In cases of significant tissue invasion or metastasis, complete tumor removal may not be possible...

BACKGROUND: Bcl-2-associated athanogene 3 (BAG3), a co-chaperone of heat shock protein 70 (HSP70), has been shown to play a role in anti-apoptosis of various malignant tumors. In this study, the expression of BAG3 was examined in human sebaceous gland carcinoma of the eyelid. MATERIALS AND METHODS: The expression of BAG3 was evaluated by immunohistochemistry of surgical samples from 5 patients with sebaceous gland carcinoma in the eyelid. RESULTS: BAG3 was positive diffusely in the cytoplasm in all patients...

Kidney transplantation is the best treatment for end-stage renal failure. It prolongs the patient's life, improves quality of life and reduces costs associated with renal replacement therapy. Increasingly, newer immunosuppressive regimens allow for the proper functioning of the transplanted organ for many years. The progress in transplantation, qualification patients in older age for the procedure and longer survival of kidney graft lead to an increase in the number of patients receiving immunosuppressive drugs...

Knowledge of staining pattern of certain immunostains might be useful in the classification of cutaneous adnexal tumors that can have clinical importance. We studied GATA3 and MYB expression in archival materials of 220 adnexal tumors comprised of sebaceous carcinomas, follicular tumors, apocrine carcinoma, predominantly apocrine tumors, predominantly eccrine tumors, and others including adenoid cystic carcinomas. Nuclear GATA3 expression was seen in 70% (153/220) of cases, including sebaceous carcinoma (93%), apocrine carcinoma (93%), follicular neoplasms (100%), and predominantly apocrine neoplasms (69%), yet only 38% of predominantly eccrine neoplasms...

The histopathological diagnosis of periocular sebaceous carcinoma can be difficult in poorly differentiated cases showing few mature sebocytes. The authors examined 50 periocular sebaceous carcinomas from 46 patients to determine the frequency of 2 features seen in this neoplasm, namely cells with squared-off nuclei and so-called "appliqué" pattern (peritumoral subnecrosis of peripherally located neoplastic cells). Neoplastic cells with squared-off nuclei were found in varying numbers in both the intraepithelial and dermal (invasive) components in all neoplasms, whereas the appliqué pattern was observed in a third of the cases...
