1/126. Sclerosing sweat duct carcinoma of the eyelid margin: unusual presentation of a rare tumor.OBJECTIVE: Sclerosing sweat duct carcinoma (SSDC) is a rare, slow-growing, locally invasive skin tumor of eccrine and pilar origin. It is usually located on the face, particularly the upper lip, cheek, and forehead. It has been infrequently reported on the eyelid, secondarily involved from adjacent cheek and brow tumors. Only four previous cases have reported primary eyelid tumors. The authors present four cases of primary eyelid margin involvement, which show the variability in clinical presentations. DESIGN: Retrospective case series. The authors present four case studies of lower eyelid margin tumors diagnosed as SSDC. PARTICIPANTS/methods: The history of this recently recognized neoplasm is discussed in relation to the cases presented and the role of the ophthalmologist and pathologist in such cases. RESULTS: Primary SSDC of the eyelid margin is a reportedly rare entity. This particular presentation can occur in all age groups; can mimic benign, acanthotic, or basal cell-like tumors; and is usually misdiagnosed initially. This can lead to a delay in definitive treatment for a tumor that classically presents late in its natural history to health professionals. All eight cases of primary eyelid SSDC now reported in the literature have occurred in the lower lid. CONCLUSION: This rare but aggressive tumor is difficult to diagnose from a simple biopsy and may be more common than previously believed. Initial or early diagnosis is important because of unusually invasive characteristics. recurrence is common and usually leads to extensive tissue loss via direct invasion or subsequent wide resection. Correct histologic diagnosis at the time of initial tumor removal will likely aid in achieving complete excision with fewer recurrences.- - - - - - - - - - ranking = 1keywords = sweat (Clic here for more details about this article) |
2/126. Primary eyelid mucinous adenocarcinoma of eccrine origin.To report a case of mucinous adenocarcinoma of the eyelid. A 70-year-old man presented with a lesion of his lower left eyelid, which had been growing over the past few years. An excisional biopsy was performed. The lesion was incompletely excised and recurrence at the excision site was observed at a 3-month follow-up visit. A histopathological examination of the excised specimen showed it to be a mucinous adenocarcinoma of eccrine origin. Primary mucinous adenocarcinoma of the eye lid is a rare malignant sweat gland tumor with a high incidence of local recurrence. It has to be differentiated from other adenocarcinomas which may rarely metastasize to the skin.- - - - - - - - - - ranking = 2.93291658815keywords = sweat gland, sweat, gland (Clic here for more details about this article) |
3/126. Mucoepidermoid carcinoma of the eyelid skin.PURPOSE: Mucoepidermoid carcinoma involving the eye or its adnexa generally arises from the conjunctiva. We describe a nodular lesion of the lower eyelid skin with histologic features consistent with low-grade mucoepidermoid carcinoma. METHOD: Case report. RESULTS: By histology, the tumor demonstrated areas of squamous cell carcinoma and scattered islands of mucin-secreting cells. Histochemistry showed hyaluronidase-resistant mucin and intense immunoreactivity with an antibody against carcinoembryonic antigen suggesting that the tumor originated from acrosyringeal structures. CONCLUSIONS: To our knowledge, this is the first report of a mucoepidermoid carcinoma arising from sweat glands in the eyelid skin.- - - - - - - - - - ranking = 2.93291658815keywords = sweat gland, sweat, gland (Clic here for more details about this article) |
4/126. Sebaceous adenoma in the region of the medial canthus causing proptosis.A case of sebaceous adenoma in the region of the medial canthus causing proptosis is presented along with a review of the medical literature. The clinicopathological aspects of the tumour are discussed. The mode of treatment was surgical excision. A six month follow-up showed a reduction in the proptosis with no recurrence.- - - - - - - - - - ranking = 0.010357416935784keywords = adenoma (Clic here for more details about this article) |
5/126. Clear cell hidradenoma of the eyelid: a case report.Sweat gland tumours are extremely rare in the eyelids. We report a case of a clear cell hidradenoma (nodular hidradenoma) in an elderly female, who had presented with a nodular swelling in a eyelid. Clear cell hidradenomas arise as intradermal nodules from eccrine sweat glands. Ultrastructural and enzyme histochemical studies have shown nodular hidradenomas to be intermediate between eccrine poroma and eccrine spiradenoma. No apocrine differentiation has ever been observed in these tumours. Malignant forms are distinctly unusual. This case is being documented for the extremely uncommon presentation of this tumour as an eyelid mass. Complete primary excision is advocated and local steroid preparations should bot be used.- - - - - - - - - - ranking = 2.9871295197328keywords = sweat gland, sweat, gland, adenoma (Clic here for more details about this article) |
6/126. Primary cutaneous adenoid cystic carcinoma of the eyelid.PURPOSE: To report a case of primary cutaneous adenoid cystic carcinoma involving the eyelid. methods: We examined a 70-year-old woman with an 18-month history of a gradually enlarging, blue-colored mass in the medial third of the right upper eyelid. Excisional biopsy and additional resection of the medially infiltrated margin resulted in tumor-free edges. Superior cervical and orbital evaluations were performed. RESULTS: Histopathologic evaluation revealed a primary cutaneous adenoid cystic carcinoma. No gland pathology was documented. No tumor recurrence has been noted. CONCLUSION: Primary cutaneous adenoid cystic carcinoma, an uncommon tumor of the skin, should be added to the differential diagnosis of eyelid tumors.- - - - - - - - - - ranking = 0.035569581098444keywords = gland (Clic here for more details about this article) |
7/126. Second malignant neoplasms of the head and neck in survivors of retinoblastoma.retinoblastoma is a malignant tumor of the embryonic retina. Although it is rare, it is the most common primary eye tumor of childhood. life expectancy following treatment is now excellent, but survivors who have heritable retinoblastoma face an increased risk of a second malignant head or neck neoplasm. A second neoplasm, which often occurs in the irradiated field of the original tumor, has become the most significant threat to the survival of these patients. We report the case of a young girl who was cured of her retinoblastoma only to later develop a second nonocular tumor that metastasized to the superficial parotid gland. She underwent a superficial parotidectomy and neck dissection, but the malignancy eventually recurred and required further surgery and radiation therapy. In this article, we discuss the etiology, incidence, sites of occurrence, and management options for a second malignant neoplasm in retinoblastoma survivors. The head and neck surgeon must be vigilant in the diagnosis and management of second neoplasms in this patient population because they often occur in irradiated fields; surgical management is important to patient survival.- - - - - - - - - - ranking = 0.035569581098444keywords = gland (Clic here for more details about this article) |
8/126. Chondroid syringomas of the eyelid: two cases.PURPOSE: We report two new cases of chondroid syringoma (CS) of the eyelid. Until 1961, this entity was known as pleomorphic adenoma or benign mixed tumour of the skin of salivary glands type. This tumour occurs most commonly in the head and neck regions. case reports: We describe two cases of CS with rapid growth, in the upper right eyelid, with no relation with the palpebral lobe of the lacrimal gland. RESULTS. Treatment consists of wide local surgical excision with its capsule, in its entirety. CONCLUSIONS: These tumours of the ocular adnexa are exceedingly rare. Malignant transformation is possible.- - - - - - - - - - ranking = 0.073210645584046keywords = gland, adenoma (Clic here for more details about this article) |
9/126. Non-Hodgkin's lymphoma & primary biliary cirrhosis with sjogren's syndrome.sjogren's syndrome (SS) is an autoimmune disease characterized by a lymphocytic infiltration of the salivary and lacrimal glands leading to a progressive destruction of these glands due to the production of autoantibodies. This disorder is either isolated (primary SS) or associated with other systemic diseases (secondary SS). The occurrence of B-cell non-Hodgkin's lymphoma (NHL) represents the major complication in the evolution of SS patients. The risk of developing NHL, which is equivalent for both primary and secondary SS, was estimated to be 44 times greater than that observed in a comparable normal population. NHLs in SS patients occur preferentially in the salivary glands and in other mucosa-associated lymphoid tissues (MALT). However, it can also occur in the lymph nodes or bone marrow. We documented a case of low-grade B-cell lymphoma of MALT in the right eyelid and primary biliary cirrhosis (PBC) of a patient with SS. To the best of our knowledge, this is the first case reported in korea.- - - - - - - - - - ranking = 0.10670874329533keywords = gland (Clic here for more details about this article) |
10/126. Eccrine poroma of the eyelid.A clinicopathological case report of a 71-year-old Caucasoid man with an unusual right lower eyelid lesion, which proved to be an eccrine poroma, is presented. Benign eccrine poromas have not previously been reported to occur on the eyelid. Compete surgical excision of this lesion proved to be curative, with no recurrence after 3 years follow up. Eccrine poromas are common benign tumours of the intraepidermal sweat duct unit. sweat glands occur commonly on the eyelids and eccrine poroma should be considered in the differential diagnosis of eyelid tumours.- - - - - - - - - - ranking = 0.23556958109844keywords = sweat, gland (Clic here for more details about this article) |
