We examined dermoscopic features of three cases of extraocular sebaceous carcinoma and reviewed the literatures. The yellowish structures, polymorphous vessels and ulceration were common findings in our cases and all cases of the previous reports. The appearance of whitish-pink areas has not been described previously. Our results suggested that the combination of four dermoscopic features, whitish-pink areas, yellowish structures, polymorphous vessels and ulceration might be distinctive in extraocular sebaceous carcinoma...

Organ transplant recipients (OTRs) are a population at high risk for cutaneous adverse events. Their early recognition and appropriate treatment is an important component of the clinical management of OTRs and should be optimally dealt with by dermatologists working in the context of a transplant dermatology clinic. Skin examination should be a standard procedure before performing organ transplantation to assess conditions which may be difficult to manage after the transplant procedure has been performed or which may represent a contraindication to transplantation, e...

PURPOSE: Overexpression of the inhibitors of apoptosis proteins have been demonstrated in a variety and of solid tumors including melanomas and nonmelanomas skin cancers. X-linked inhibitor of apoptosis protein (XIAP) is an inhibitor of apoptosis which prevents apoptosis by inhibiting caspases 9, 7, and 3. The prognostic value of XIAP in sebaceous gland carcinoma (SGC) remains unexplored. METHODS: The immunohistochemical expression of XIAP was evaluated in 29 SGC cases...

Renal cell carcinoma (RCC) is the third most common genitourinary malignancy with an estimated one third of cases with metastatic disease at the time of diagnosis. Though rare, cutaneous metastasis from RCC is more frequent than any other genitourinary malignancy. Metastasis of RCC to skin carries poor prognosis as coexistent visceral spread is the norm. A 38-year-old man presented one year after radical nephrectomy for clear cell carcinoma of the left kidney with a submental lesion that proved to be metastatic...

Although basal cell carcinoma (BCC) is a common skin tumor, very rare cases of BCC arising from upper vermilion mucosa of lip have been reported previously. This tumor basically, originates from pillar structures and the involvement of the vermilion lip contrasts this concept so it is devoid of hair follicles and sweat glands. The exact pathogenesis of vermilion lip BCC is not clear but it has been postulated that the neoplasm originates from the pluripotential epithelial cells of the oral mucosa and epidermis...

Sebaceous differentiation is commonly seen in cutaneous neoplasms, both in the context of lesions showing predominantly sebaceous differentiation (e.g., sebaceous adenoma, sebaceoma and sebaceous carcinoma), or as more focal sebaceous components in neoplasms with other primary lines of differentiation. Sebaceous changes can also be a component of benign cystic lesions or epidermal tumours, and sebaceous hyperplasia is commonly encountered. This review is intended to provide an overview of the cutaneous lesions with sebaceous differentiation, with a particular emphasis on facilitating histological diagnosis of neoplasms...

CONTEXT: - Basal cell carcinoma (BCC) is the most common human malignant neoplasm and is a frequently encountered diagnosis in dermatopathology. Although BCC may be locally destructive, it rarely metastasizes. Many diagnostic entities display morphologic and immunophenotypic overlap with BCC, including nonneoplastic processes, such as follicular induction over dermatofibroma; benign follicular tumors, such as trichoblastoma, trichoepithelioma, or basaloid follicular hamartoma; and malignant tumors, such as sebaceous carcinoma or Merkel cell carcinoma...

Microcystic adnexal carcinoma (MAC) is a rare malignancy of sweat glands that has been reported most often on the face in the form of a cutaneous lesion, with the potential for deeper invasion. The synonyms of MAC include sclerosing sweat duct carcinoma, syringomatous carcinoma, and malignant syringoma. Clinically, MAC in the periocular area has been misdiagnosed as basal cell carcinoma, squamous cell carcinoma, or even chalazia. We report a case of MAC presenting clinically as sebaceous gland carcinoma with pagetoid spread for the first time in literature...

Although carcinoma in situ has been accepted as a well-established concept and diagnostic category, for reasons unknown sebaceous carcinoma in situ has not been recognized yet in general pathology or dermatopathology. Such lesions have always been misinterpreted as either benign neoplasm or sebaceous carcinoma. In the present essay, we provide a convincing account supporting sebaceous carcinoma in situ as a valid concept and diagnostic entity via critical literature review and histopathological assessment and illustration...

Malignant cutaneous adnexal neoplasms form a group of rare, typically low-grade-malignancy carcinomas with follicular, sebaceous, apocrine, or eccrine differentiation or a combination of the first 3 subtypes. Their clinical presentation is usually unremarkable, and biopsy is required to establish the differentiation subtype and the definitive diagnosis. Due to their rarity, no clear consensus has been reached on which treatment is most effective. Mohs micrographic surgery is considered to be the best option to prevent recurrence in the majority of patients...

Phacomatosis pigmentokeratotica is a recently identified disease characterized by the coexistence of an epidermal nevus with sebaceous differentiation arranged along Blaschko lines and a speckled lentiginous nevus showing a checkerboard pattern, mostly in association with various extracutaneous defects. A 52-year-old man presented with asymptomatic ulcerative plaque on his left side of perioral area. A 2 × 2-cm-sized fleshy colored ulceration on his left perioral area was consistent with basal cell carcinoma with nevus sebaceous...

Pilomatrix carcinoma is a rare, locally aggressive tumor with a tendency to recur. Distant metastases have been reported, with pulmonary lesions being the most frequent manifestation. Similar to pilomatrixoma, pilomatrix carcinoma typically presents as a nontender, firm dermal swelling and is found most commonly in the head and neck region. Although pilomatrixomas and pilomatrix carcinoma are well-recognized lesions, clinically they are frequently misdiagnosed as other skin conditions. By reviewing the literature over the past 10 years, the aims of this review are to analyze the cause, clinical presentation, histopathologic features, management and outcomes of pilomatrix carcinoma amongst children and adults...

Nevus sebaceus is a hamartoma of the sebaceous gland that occurs congenitally, from which various secondary tumors can arise with a prevalence of 5%-6%. Benign neoplasms commonly arise from nevus sebaceous, but they have a very low malignant potential. Two neoplasms may occasionally arise within the same lesion, but it is rare for three or more neoplasms to occur in a nevus sebaceus simultaneously. A 61-year-old male patient was admitted to our hospital for a 4 cm×2.5 cm growing tumor in a verrucous form arising within a periauricular nevus sebaceus in the post auricle of the left ear that had developed 30 years earlier...

Nevus sebaceus of Jadassohn is a congenital tumour affecting the scalp and face. It is usually presented as a pigmented patch or plaque. It is a complex cutaneous hamartoma which involves pilosebaceous follicle, epidermis and adnexal structures. Tumours that arise from nevus sebaceous are basal cell carcinoma, syringocystadenoma papilliferum, trichoblastoma and hidradenoma. The progression and frequency of the tumour increase with the age. Here we present a case of pigmented trichoblastoma over the external nose...

BACKGROUND: Reliable nuclear immunohistochemical stains for sebaceous neoplasms have not been readily available. Positive nuclear staining has been reported by GATA3 and factor XIIIa (AC-1A1). We sought to determine the diagnostic utility of these nuclear stains by comparing their staining pattern to adipophilin, a consistently positive cytoplasmic stain. METHODS: Cases with the diagnosis of sebaceous hyperplasia, sebaceous adenoma, sebaceous epithelioma/sebaceoma, and sebaceous carcinoma, nonsebaceous neoplasms (basal cell carcinoma and squamous cell carcinoma) were examined...

Muir-Torre syndrome is a rare genodermatosis inherited most frequently in an autosomal dominant fashion. Current criteria for its diagnosis include at least one sebaceous tumor and an underlying visceral malignancy. Muir-Torre syndrome is strongly associated with a germline mutation in DNA mismatch repair genes. We report two patients with a history of colorectal carcinoma who presented with sebaceous neoplasms on the face and trunk. Immunohistochemical staining of the sebaceous neoplasms demonstrated absence of mismatch repair proteins MSH2 and MSH6...
