PURPOSE: To report a rare case of sebaceoma misdiagnosed as chalazion. CASE SUMMARY: A 42-year-old female presented with a visible mass in her right lower eyelid. An elevated, hard mass was located at the margin of the right lower eyelid, and she had a history of incision and curettage under the clinical impression of chalazion. On eversion of the lower eyelid, the tarsal portion of the mass was visible as a white-yellowish lesion. The mass was excised under local anesthesia. A sebaceoma was diagnosed based on histopathological examinations. Immunohistochemical studies showed positive staining results for mutator L homologue 1 (MLH1), mutator S homologue 2 (MSH2), and mutator S homologue 6 (MSH6), and she had no past medical history or family history of internal malignancy, suggesting a low possibility of Muir-Torre syndrome. CONCLUSIONS: Eyelid sebaceoma should be considered as a differential diagnosis for refractory chalazion.

Muir-Torre Syndrome*

Sebaceous carcinoma is a very rare and potentially aggressive carcinoma originating from the epithelial lining of the sebaceous gland. More than 70% of all cases are in the head and neck region, especially the periorbita; therefore, they are classified into ocular and extraocular sebaceous carcinoma. The reported risk factors are advanced age, male sex, previous irradiation, and genetic predisposition for Muir-Torre syndrome. The current case is of sebaceous carcinoma found in the suprapubic area of a 67-year-old male patient who had received liver transplantation 6 years before, and had been receiving oral tacrolimus. Examination of the gastrointestinal system did not reveal any other malignancies. Although nonmelanoma skin cancers may occur as a complication after liver transplantation, there have been no previous reports of sebaceous carcinoma after liver transplantation. Furthermore, the sebaceous carcinoma in this case occurred in an uncommon location. We report this case along with a review of the literature.

Muir-Torre syndrome is defined by concurrent or sequential development of internal malignancy and sebaceous neoplasm or multiple keratoacanthomas. Muir-Torre syndrome is very rare, with only 205 cases reported in the literature. We reported a patient with Muir-Torre syndrome with three internal malignancies. A 64-year-old patient with a history of breast cancer, stomach cancer and colon cancer visited our department for treatment of the skin lesion that occurred five years before on the left cheek. The lesion was excised completely with a resection margin of 1 cm, followed by full-thickness skin graft from left postauricular area for reconstruction. Histopathology revealed a 0.2 x 0.2 x 0.1 cm sized sebaceous carcinoma with 4 mm safety margin. The skin graft was well taken within 7 days after surgery and the patient was discharged to outpatient follow-up. There was no complication related with surgery. Muir-Torre syndrome is very rare, as are sebaceous gland tumors. So if a cancer of the sebaceous gland is diagnosed, screening workup for internal malignancy is recommended. Because of its good prognosis, surgical removal of primary or metastatic cancers may be curative and should be attempted where possible.

We report a case of Muir-Torre syndrome (MTS) with a very rare combination of cancers, involving bilateral eyelid cancers and breast cancer. A 71-year-old female with a history of breast cancer from 18 years prior presented with bilateral eyelid tumors. One of her siblings had lung cancer, and another had pancreatic cancer. She underwent excisional biopsy of the eyelid tumors and histopathology revealed sebaceous carcinoma of the right eyelid and basal cell carcinoma of the left. She was diagnosed with MTS: a skin cancer associated with visceral malignancy. Immunohistochemical tests for mutS homolog 2 showed a lack of expression in both eyelid carcinomas.

PURPOSE: To present a rare case of Muir-Torre syndrome characterized by the association of sebaceous skin tumors and systemic malignancies. CASE SUMMARY: A 65-year-old female visited our clinic with an irregular nodular mass of the right lower eyelid, which developed 1 year earlier. An excisional biopsy and lower lid reconstruction with Tenzel's semicircular rotational flap was performed under local anesthesia. Histopathologic examination showed well-differentiated sebaceous cells, consistent with sebaceous adenoma. The patient had undergone total abdominal hysterectomy and lower anterior resection due to endometrial cancer and sigmoid colon cancer 5 years before, and nephroureterectomy due to papillary urothelial carcinoma 3 years before. Based on the history of systemic malignancy and sebaceous skin cancer, a diagnosis of Muir-Torre syndrome was made. CONCLUSIONS: When a sebaceous gland tumor of the eyelids is detected, Muir-Torre syndrome should be included in the differential diagnosis, and systemic work-up for the internal malignancy must be performed.

Muir-Torre syndrome is defined by concurrent or sequential development of internal malignancy - most commonly colorectal cancer - and sebaceous neoplasm or multiple keratoacanthomas. Recent studies revealed it was caused by mutations in DNA mismatch repair genes, and suggested screening for mismatch repair gene defects may be of value for patients with Muir-Torre syndrome. We, herein, report a patient with Muir-Torre syndrome, who developed breast cancer and extra-ocular sebaceous carcinoma. In addition, we discussed our experience of immunohistochemical staining for mismatch repair protein with a review of the literature.

Muir-Torre syndrome (MTS) is an autosomal dominant genodermatosis characterized by at least one rare sebaceous neoplasm occurring in association with at least one internal malignancy. The visceral neoplasms most frequently associated with MTS are colorectal and genitourinary cancer, accounting for approximately 50 and 25% of cases, respectively. MTS rarely occurs in association with head and neck cancers. We report a rare case of MTS involving follicular thyroid carcinoma in an 84-year-old female.

Muir-Torre syndrome (MTS) is a rare autosomal dominant genodermatoses, first described in 1967. It is characterized by the presence of sebaceous tumors and an internal malignancy in the absence of other predisposing factors. The most common internal malignancy associated with MTS is colorectal adenocarcinoma, although a wide tumor spectrum exists including carcinomas of the genitourinary tract, breast, and hematologic malignancy. It is rare for more than two internal malignancies to occur in MTS. We report a rare case of MTS with B-cell lymphoma, esophageal cancer and gastric malignancy in a 63-year-old male.
