Sweat-gland carcinoma is a rare cutaneous appendage malignant tumor. Primary sweat-gland cancer can arise in the eyelid and orbit and is extremely rare. It has been classified into different types, and is usually locally recurrent after surgery. The tumors also appear in the orbit, which is characterized by metastasis. Therefore, great attention should be paid to the development of sweat-gland ...

A 12-year-old Belgian draft horse presented for a right eye third eyelid mass and red-tinged ocular discharge of 3 months' duration. The third eyelid was excised and submitted for histopathology. On histopathologic examination, the mass was composed of both hemangiosarcoma and squamous cell carcinoma. The horse developed thickened eyelids and hemorrhagic ocular discharge from the right eye appr...

Conjunctival malignant melanoma is a rare tumor with a high risk of local recurrence, lymph node and systemic metastases. The aim of this study was to correlate tumor thickness, tumor ulceration, high mitotic rate, epithelioid cells with the presence of metastases and death from conjunctival malignant melanoma. We report the case of a 33-year-old patient who presented with a left eyelid ptosis ...

A case is reported in which a testicular cancer presented as a metastatic deposit in the eyelid. The histological appearances of both the metastasis and the subsequently detected primary were diagnostic of malignant teratoma trophoblastic (MTT). After comments on the testicular tumour, metastases occurring in the eye and adnexa are discussed.

PURPOSE To review the findings, management, and outcome in 33 cases of primary ophthalmic rhabdomyosarcoma. METHODS The records of 33 consecutive patients from a single ocular oncology center were analyzed retrospectively for outcomes of final visual acuity, local recurrence, and distant metastasis. RESULTS Rhabdomyosarcoma was primarily located in the orbit m 25 cases (76%), conjunctiva in...

A clinicopathologic study of 31 squamous cell carcinomas of the eyelid was conducted. The tumor was encountered less frequently than in previous reports, due largely to the refinement of the pathologic diagnosis. Eighteen cases originally diagnosed as squamous cell carcinoma were eliminated because the diagnoses were changed to sebaceous gland carcinoma (10), basal cell carcinoma (4), seborrhei...

BACKGROUND Sebaceous cell carcinoma is a distinctive tumor of the eyelid associated with a high rate of metastasis and mortality. Involvement of both upper and lower lids has been described; however, involvement of all 4 eyelids is extremely rare. OBJECTIVE To describe the evaluation and diagnosis of the clinicopathologic features in a 74-year-old patient with 4-eyelid sebaceous carcinoma and...
