Topical mitomycin-C for pagetoid invasion of the conjunctiva by eyelid sebaceous gland carcinoma

PURPOSE: To evaluate the efficacy of topical mitomycin-C for pagetoid invasion of the conjunctiva by sebaceous gland carcinoma. DESIGN: Prospective noncomparative consecutive interventional case series. INTERVENTION: All patients received topical 0.04% mitomycin-C four times daily for 1 week followed by 1 week off medication. The treatment cycles were repeated until resolution of the conjunctival malignancy was clinically evident. PARTICIPANTS: Four patients with histopathologically proven intraepithelial (pagetoid) invasion of the conjunctiva by sebaceous gland carcinoma were managed with this regimen. RESULTS: The mean patient age was 78 years. Before treatment, the main tumor site included the upper eyelid in two cases and the lower eyelid in two cases. Previous resection of the tumor had been performed elsewhere in three cases over the prior 6 years. At the time of our examination, map biopsies confirmed pagetoid invasion involving 25% to 90% of the conjunctival surface, with bulbar, forniceal, and tarsal conjunctival involvement in all four cases and corneal extension in one case. There was no evidence of deep tumor within the conjunctival stroma or tarsus in any case. After treatment, medication intolerance and early discontinuation occurred in one patient, and continued tumor progression was documented. Of the remaining three patients, chemotherapy was used for a mean of four cycles with complete resolution of the pagetoid invasion, confirmed histopathologically in two cases, and without recurrence in all three cases over 12 months (mean) follow-up. The medication caused moderate temporary local irritation but no serious intraocular or extraocular complications. CONCLUSIONS: Preliminary evidence suggests that topical mitomycin-C is effective treatment for pagetoid invasion of the conjunctiva by sebaceous gland carcinoma. Longer follow-up is necessary to assess the duration of tumor control.     

Outcome of patients with periocular sebaceous gland carcinoma with and without conjunctival intraepithelial invasion

PURPOSE: To evaluate the clinical findings, histopathologic features, methods of management, and outcomes in 25 patients with eyelid sebaceous gland carcinoma with and without conjunctival intraepithelial (pagetoid) invasion. PARTICIPANTS: Twenty-five patients with sebaceous gland carcinoma of the periocular region. DESIGN: Retrospective, observational case series. METHODS: The patients were divided into two groups: group A included those with sebaceous gland carcinoma with conjunctival intraepithelial (pagetoid) invasion, and group B included those with sebaceous gland carcinoma without conjunctival intraepithelial invasion. The demographic, clinical, and histopathologic features of sebaceous gland carcinoma were reviewed separately for each group. Ocular management results and systemic prognosis were reviewed. RESULTS: Of the 25 patients, 18 (72%) were females and 7 (28%) were males. The mean age at diagnosis was 65 years (range, 17-90 years). There were 11 patients (44%) in group A, and 14 (56%) in group B. The most common symptom in group A was ocular irritation (45%), and in group B the most common symptom was eyelid lump (86%). The most common sign in group A was diffuse eyelid thickening (72%), and in group B the most common sign was a distinct eyelid mass (43%). Six patients (55%) in group A, compared with one patient (7%) in group B, had both upper and lower eyelid involvement. The most frequent location of tumor epicenter was the outer third of the eyelid in both groups: 37% in group A and 57% in group B. Histopathologic origin of tumor was multicentric in four patients (36%) of group A and six patients (50%) of group B. Before referral, local recurrence had been found in 4 of 12 patients (33%) who underwent surgical treatment elsewhere. After referral, local recurrence was detected in 1 patient (9%) in group A and in 2 patients (14%) in group B. Orbital exenteration was necessary in 4 patients (36%) in group A and in one patient (7%) in group B. Tumor-related metastases occurred in two patients (18%) in group A and in two patients (14%) in group B. CONCLUSIONS: Sebaceous gland carcinoma with conjunctival intraepithelial (pagetoid) invasion has different clinical features compared with that without pagetoid invasion. Conjunctival intraepithelial (pagetoid) invasion carries a higher risk for orbital exenteration, but the risk of tumor-related metastases is similar in both groups.     

Intraepithelial sebaceous carcinoma of the conjunctiva and skin of the eyelid.

The authors report a 65-year-old woman with a 10-year history of conjunctivitis and progressive loss of lashes due to widespread intraepithelial sebaceous carcinoma of the conjunctiva and skin of the eyelid. After surgery, serial sections of the entire conjunctiva and eyelids showed a single focus of invasive carcinoma in the bulbar conjunctiva, which probably arose from the epithelium. The absence of cilia on the affected lower lid was associated with neoplastic obliteration of the cilial orifices and low-grade, smoldering lipogranulomatous inflammation. This type of tumor-related alopecia is likely to masquerade as blepharitis because there is no identifiable tumefaction or clinical evidence of recurrent chalazia to suggest an underlying sebaceous carcinoma. The 10-year history of "conjunctivitis" before diagnosis indicates that intraepithelial sebaceous carcinoma may have a prolonged clinical course.     

Solitary extramedullary plasmacytoma of the palpebral conjunctiva.

A 63-year-old man had a solitary extramedullary plasmacytoma of the conjunctiva for several years with no history of ocular inflammation or systemic abnormalities. Immunoperoxidase staining was consistent with a neoplastic lesion. This is the only well documented such case in the recent literature to the best of our knowledge. This rare condition is contrasted with reactive plasma cell granuloma, a benign inflammatory condition, which comprises most of the cases previously reported as plasmacytomas. Since extraskeletal plasmacytomas may be the first manifestation of multiple myeloma, these patients deserve appropriate diagnostic evaluation and close follow-up.     

Case of atypical fibroxanthoma in the palpebral conjunctiva

Background  We report a case of atypical fibroxanthoma that developed in the palpebral conjunctiva. Case  A 94-year-old woman had a hemorrhagic tumor in the right lower palpebral conjunctiva that was resected, and adjunctive cryotherapy was applied to the surgical bed. Observations  The tumor was bleeding and appeared as a pale red, elastic but firm nodule approximately 15 × 16 × 8 mm in size. It was composed mainly of fibroblast-like cells and pleomorphic histiocyte-like cells. A storiform pattern was observed in the fibroblast-like cells. The tumor stained positive for vimentin, CD68, and CD10, weakly for CD74 and CD99, and was negative for keratin (wide), KL-1, α-fetoprotein, myoglobin, S-100, α-smooth muscle actin, desmin, leukocyte common antigen, and glial fibrillary acidic protein immunohistochemically. The MIB-1 index was about 10%. From these findings, we diagnosed the tumor as an atypical fibroxanthoma. There has been no recurrence in the 2 years since the resection. Conclusions  An atypical fibroxanthoma in the palpebral conjunctiva is very rare. The clinical presentation and histological and immunohistochemical studies are helpful in distinguishing between an atypical fibroxanthoma and a malignant fibrous histiocytoma.
