The Usefulness of Dermoscopy in Extraocular Sebaceous Carcinoma (original) (raw)
Extraocular sebaceous carcinoma of neck: A case Report
Context: Sebaceous cell carcinoma is a malignant neoplasm, rarely recognized in extra ocular sites. This neoplasm is aggressive in 29% of patients, lymph node and visceral metastasis are common. Its prognosis depends on early diagnosis of lesion. Clinical &Diagnostic features: An 49 year old female had slow growing nonulcerative subcutaneous nodule on the nape of neck of 9 months duration. On FNAC cytological findings favoured a benign skin adenexal tumor with focal nuclear atypia. On histological examination it was diagnosed as a poorly differentiated sebaceous carcinoma. Conclusion: Extra ocular sebaceous carcinoma is a rare neoplasm. It is difficult to diagnose as it has diverse clinical presentations, histologic patterns and complicated nomenclature. We will discuss the incidence, clinical, and histological findings along with the prognosis of this aggressive neoplasm.
Sebaceous carcinoma of the eyelid: anatomoclinical data
Romanian journal of morphology and embryology = Revue roumaine de morphologie et embryologie, 2013
Sebaceous gland carcinoma of the eyelid is a rare slow-growing tumor and is one of the most aggressive malignancies of the eyelid. Diagnosis is often delayed because it can be confused with other periocular lesions. We report the case of a 78-year-old female who presented for the anesthetic aspect of a nodular tumor on the right upper eyelid occurring one year earlier. The patient was treated for three months for recurrent chalazion. Ophthalmologic examination revealed a nodular ulcerated tumor of 1 cm in size adherent to adjacent tissues. Surgical excision was performed with a safety margin of 4 mm. The diagnosis of moderately differentiated sebaceous carcinoma was made by routine morphological methods and immunohistochemical reactions (EMA and Ki-67). Being a rare tumor with considerable morbidity and mortality, early diagnosis and proper treatment are essential for a favorable prognosis and preservation of visual function.

Purpose Sebaceous carcinoma (SC) is a rare adnexal tumor. Extra-ocular, facial SC is very uncommon and local metastases are an extreme rare finding. A respective case is presented and discussed together with the current literature. Case and Review A tumor of the left ear of an 87-old male was primary excised together with multiple suspicious lesions of the head and neck. Most specimens were histopathologically rated as squamous cell carcinomas (SCC). Despite the in-sano resection, additional new suspicious retro-auricular and temporal lesions were detected. Successive resections were diagnosed as basal cell carcinomas (BCC) and, because of a non-in-sano resection in a third approach, as SC. After reappraisal and immunhistochemical staining [epithelial membrane antigen (EMA), CK 5-6 and CD 15], most of the former specimens turned out to be SC as well. A literature search showed 3 reported cases of extra-ocular head and neck SC with cutaneous local metastases. In another review, in a total of 168 cases, SC was diagnosed after wrong initial histological diagnosis (SCC n = 56, BCC n = 44; other entity or precursors of carcinomas n = 68).
Sebaceous carcinoma in situ as a diagnostic entity. Case report and review of the literature
Albanian Journal of Trauma and Emergency Surgery
The concept of carcinoma in situ was first introduced by Broders in 1932 [1] and has been accepted as a well-established notion and diagnostic category in many organs and systems. However, sebaceous carcinoma in situ (SCIS) has not yet been recognized as a concept and diagnostic entity in general pathology or dermatopathology. Such lesions have been commonly misinterpreted as either a benign neoplasm or sebaceous carcinoma. Tumors that do not necessarily arise in pre-existing sebaceous glands are usually invasive at the time of diagnosis, and like their ocular counterparts, can exhibit pagetoid intraepidermal spread. Cases of purely in- situ extraocular sebaceous carcinoma are extremely rare and yet controversial until now.Recognizing sebaceous carcinoma in situ as a valid concept and diagnostic entity that will certainly help to avoid misinterpretation and subsequently under or over treatment of such lesions.In this article, we provide a case report presentation with histopathologi...

A 40-year-old woman was referred to our department due to an apparent indolent anterior blepharitis with an indurated node in her right upper eyelid, which had persisted for months. It was believed to be a chalazion associated with an ipsilateral swollen pre-aurical lymph node, which had not responded to conventional treatment. The extemporaneous biopsy was reported as sebaceous carcinoma. Complete exeresis was performed on that eyelid and it was reconstructed with a palate mucosa graft and a glabelar flap. A radical neck dissection was performed later, in order to remove the lymph nodes that appeared necrotic in several lymphatic areas. A biopsy was also performed on the lower eyelid, which was reported as positive for carcinomatous infiltration, and therefore it was treated with Curie-therapy. Discussion: The precocity in diagnosing sebaceous carcinomas of the eyelids is the main prognostic factor. The reconstruction in cases with need of complete eyelid exeresis is feasible by means of a palate mucosa graft. In our case, both the anaplastic character and the high aggressiveness of the neoplasm were a therapeutic challenge.
Metastatic extraocular sebaceous carcinoma with an occult primary
Diagnostic Cytopathology, 2004
The cytological diagnosis of sebaceous carcinoma is based on the aspiration of tumor lobules with extensive sebaceous differentiation. However, these tumors may show a spectrum of cells ranging from basaloid to well-differentiated sebaceous. Extraocular sebaceous carcinoma is an uncommon tumor. An occult primary at initial presentation has not been described previously. A 60-yr old woman was referred to the fine-needle aspiration (FNA) clinic with a submandibular mass. The cytological diagnosis was mucoepidermoid carcinoma. Histopathologically, it was a sebaceous carcinoma metastatic to the submandibular lymph node. No primary tumor was identified. Six months later, she presented with a nodule at the angle of her mouth and a recurrence of the submandibular swelling. FNA cytology (FNAC) and histopathologic examination revealed a primary cutaneous sebaceous carcinoma with submandibular lymph node metastasis. A metastatic sebaceous carcinoma in the submandibular region with limited sebaceous differentiation and occult primary is another pitfall in the cytomorphological diagnosis of mucoepidermoid carcinoma.

Role of fine needle aspiration cytology in diagnosis of eyelid sebaceous carcinoma
Indian journal of ophthalmology
Sebaceous carcinoma of the ocular adnexa is a malignant neoplasm which can exhibit aggressive local behavior and can metastasize to regional lymph nodes and distant organs. The neoplasm is known to masquerade as other benign and less malignant lesions, resulting in delay in diagnosis and relative high morbidity and mortality. Fine needle aspiration cytology (FNAC) of recurrent upper eyelid nodules treated elsewhere as chalazion was done. Cytological smears were suggestive of malignancy. Subsequently histopathology confirmed the diagnosis of sebaceous gland carcinoma. Eyelid reconstruction was done after histopathologically confirmed tumor-free margins. The article highlights the role of FNAC in early diagnosis and subsequent appropriate surgical management of eyelid sebaceous gland carcinoma to prevent recurrence and metastasis.
Metastatic extraocular sebaceous carcinoma: a case report and review of literature
2022
Background: Sebaceous carcinomas are rare, aggressive, malignant tumors that arise from sebaceous glands. They can be ocular or extraocular. They exhibit a variety of histologic growth patterns and diverse clinical presentations. Metastases are rarely reported. Observation: A 79 year old woman presented to our department with a quickly enlarging nodule involving the mid part of her forehead 2 weeks before admission. Histological examination found a sebaceous carcinoma. The patient underwent a total excision of the lesion, and was scheduled for Radiotherapy. She was lost to follow and returned 6 months later with a right latero cervical mass related to lymph node metastasis. Conclusion: Extraocular sebaceous carcinomas represent about 25% of all sebaceous carcinomas. The available literature on treatment recommends wide surgical excision with tumor-free margins with removal of regional lymph nodes, followed sometimes by adjuvant radiotherapy. Unlike our case where the evolution was quickly aggressive, these tumors were classically considered to be a less offensive neoplasm than their ocular equivalent.
