11/289. Extensive destruction of the eyeball by invasion of basal cell carcinoma of the eyelid.BACKGROUND: Eyeball destruction caused by invasion of basal cell carcinoma of the eyelid. CASE: A 100-year-old woman showed extensive eyeball destruction caused by the invasion of basal cell carcinoma of the eyelid. Complete ophthalmologic examinations, including computed tomographic (CT) scans of the orbit, were performed. The patient underwent incisional biopsy and bacteriological examination of the exudate from the lesion. OBSERVATIONS: Orbital CT scan showed a mass in the extraconal space of the right orbit, with extension to the adjacent sinus cavity without brain involvement. The remnant of the eyeball was posteriorly displaced. pseudomonas aeruginosa was identified by culture examination of the exudate. Histological study of the biopsy specimen showed basal cell carcinoma of the noduloulcerative type. CONCLUSIONS: Basal cell carcinoma of the eyelid had caused severe periorbital and eyeball destruction.- - - - - - - - - - ranking = 1keywords = cell (Clic here for more details about this article) |
12/289. 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 = 0.25keywords = cell (Clic here for more details about this article) |
13/289. Cytologic features of metastatic sebaceous carcinoma: report of two cases with comparison to three cases of basal cell carcinoma.The cytologic findings of two cases of metastatic sebaceous carcinoma are described and compared to three cases of locally recurrent basal cell carcinoma. Morphological findings for sebaceous carcinoma in fine-needle aspiration biopsy (FNAB) smears included cellular, loosely cohesive cell clusters with central necrosis, squamous pearl formation, and adjacent keratin debris. The tumor cells had moderate amounts of vacuolated cytoplasm, round to oval vesicular nuclei with clumped chromatin, nucleoli, some nuclear overlap, and numerous mitotic figures. An interesting finding was the presence of numerous multinucleated giant cells, probably responding to extravasated lipid or keratin material. In contrast, the FNAB smears of basal cell carcinoma typically were less cellular, with more tightly cohesive and smaller clusters of uniform hyperchromatic basaloid cells with high nuclear to cytoplasmic ratios, and a narrow rim of cytoplasm without vacuolization. The morphologic features of sebaceous carcinoma in FNAB smears appear to be distinct from those of basal cell carcinoma. FNAB can be a useful preoperative diagnostic technique to distinguish these two cutaneous malignancies.- - - - - - - - - - ranking = 1.625keywords = cell (Clic here for more details about this article) |
14/289. neurothekeoma palpebrae: a rare nerve sheath tumor arising in the eyelid.PURPOSE: To report a case of an eyelid neurothekeoma, a rare peripheral nerve sheath tumor. methods: Case report. RESULTS: An excisional biopsy, performed on a lesion removed from the upper eyelid of a 76-year-old woman, revealed the clinical and histopathologic features of a neurothekeoma, a tumor consisting of multiple collections of spindle cells in a myxomatous background. Immunohistochemical characterization showed positivity for NK1/C3, neuron-specific enolase, and alcian blue. CONCLUSION: neurothekeoma palpebrae should be considered in the differential diagnosis of solitary nodules of the eyelids.- - - - - - - - - - ranking = 0.17423391601999keywords = cell, spindle cell, spindle (Clic here for more details about this article) |
15/289. Invasion of the lacrimal system by basal cell carcinoma.BACKGROUND: The rate of recurrence of basal cell carcinoma (BCC) in the periorbital region is higher than that in other areas because of the spread of the tumor along barrier structures. OBJECTIVE: A better understanding of the biological behavior of BCC in this area, in particular as it relates to the lacrimal system, should improve the outcome of surgery. methods: A study was made of two cases of BCC that developed in the periorbital region and invaded the lacrimal system. RESULTS: The tumors were found to have invaded the lacrimal system along the mucosal epithelium. magnetic resonance imaging (MRI) did not suggest any abnormalities in this area. In one patient, the tumor had infiltrated the nasal cavity without destruction of the periorbital bone and nasal cartilage. A preoperative fiberscopic examination clearly demonstrated the involvement of the nasal cavity in this case. CONCLUSION: The lacrimal system is often invaded by BCC that originates from the periorbital region. physicians and surgeons need to be well aware of the possibility of such aggressive infiltration by BCC.- - - - - - - - - - ranking = 0.625keywords = cell (Clic here for more details about this article) |
16/289. A giant cell angiofibroma involving 6q.Giant cell angiofibroma, a recently proposed new clinicopathological entity, arises exclusively in the orbit in adults and histologically exhibits features intermediate between those of giant cell fibroblastoma and solitary fibrous tumor. In a typical case of giant cell angiofibroma, abnormalities of chromosome 6 with a common pattern involving 6q13 were detected together with various other chromosomal aberrations. To our knowledge, this is the first reported case of giant cell angiofibroma demonstrating chromosomal abnormalities.- - - - - - - - - - ranking = 1keywords = cell (Clic here for more details about this article) |
17/289. Primary eyelid plasmacytoma.We report a case of eyelid plasmacytoma. The patient presented with a superficial lesion on the upper left eyelid, 10x7 mm in size. Histological and immunohistochemical findings were indicative of plasmacytoma with slightly abnormal sub-epidermic plasma cell infiltrates. Immunoperoxidase staining was strongly positive for intracytoplasmic kappa light chains. No infiltration by atypical plasma cells could be documented in the bone marrow biopsy and aspirate. Skeletal survey showed no osteolytic lesions or osteoporosis. The tumor on the left eyelid was surgically removed. No radiotherapy was administered.- - - - - - - - - - ranking = 0.25keywords = cell (Clic here for more details about this article) |
18/289. Well-differentiated squamous cell carcinoma of the eyelid arising during a 20-year period.An 81-year-old man had a keratotic eyelid lesions for 20 years. He eventually sought treatment by ophthalmic plastic surgery. Clinically, the lesion resembled a keratoacanthoma. Findings from histologic examination of the excision biopsy specimen showed a squamous cell carcinoma. The lesion was completely excised. This case demonstrates the difficulty in making a correct clinical diagnosis of a keratotic eyelid lesion. Performing a histologic examination of nonregressed keratotic lesions is essential to exclude a squamous cell carcinoma.- - - - - - - - - - ranking = 0.75keywords = cell (Clic here for more details about this article) |
19/289. Squamous cell carcinoma of the lower lid in a 19-month-old girl with xeroderma pigmentosum.Squamous cell carcinoma (SCC) of the skin usually occurs in older patients and commonly develops from actinic keratosis. patients with xeroderma pigmentosum (XP) can acquire SCC at an early age. To our knowledge the youngest reported patient with XP and SCC was 8 years of age. We report a 19-month-old Lebanese girl with XP who presented clinically because of a rapidly growing mass of the medial part of her right lower lid that was biopsied and found to be squamous cell carcinoma. The mass was surgically excised with no evidence of recurrence after 2 years of follow-up. We describe our clinical experiences with this patient and have reviewed the available literature concerning XP and malignancy.- - - - - - - - - - ranking = 0.75keywords = cell (Clic here for more details about this article) |
20/289. Sebaceous cell carcinoma of the eyelid and the human immunodeficiency virus.PURPOSE: patients infected with the human immunodeficiency virus (hiv) are at increased risk for developing malignancies, which are acquired at a younger age and are more aggressive. Sebaceous cell carcinoma is a rare eyelid tumor typically occurring in the seventh decade of life. We report two cases of sebaceous cell carcinoma in young hiv-infected patients. methods: Case series and review of the literature. We describe two hiv-infected patients with sebaceous cell carcinoma of the eyelid and caruncle. The first patient was a 36-year-old woman with a 9-month history of an enlarging right lower eyelid mass. The second patient was a 34-year-old man with a 6-month history of an enlarging right caruncular mass. RESULTS: biopsy showed both masses to be sebaceous cell carcinoma. The first patient underwent Mohs' micrographic excision of the lesion followed by reconstruction of the full-thickness eyelid defect with a combination of tarsoconjunctival and myocutaneous advancement flaps. The second patient underwent exenteration because of orbital involvement. CONCLUSION: Sebaceous cell carcinoma should be considered for any suspicious eyelid lesion in young hiv-infected patients.- - - - - - - - - - ranking = 1.125keywords = cell (Clic here for more details about this article) |
