    Abstract Dermatofibromas are most frequently encountered in women on the lower extremities, often after minor trauma. A recurrent lesion of the right lower eyelid developed in a 64-year-old woman. It harbored "monster cells" that were large, with either multiple nuclei or a single, large, convoluted, and hyperchromatic nucleus. The presence of these cells does not signify a malignant transformation. The background cells were either histiocytoid (many were adipophilin positive), spindled cells, or dendritiform cells without mitoses. Factor XIIIa, CD68, and CD163 immunostaining was positive, and a subpopulation of CD1a

    Abstract We describe a case of lymphocytic panhypophysitis (LPH) in a 30-year-old woman presenting with throbbing headaches and vision changes during her third trimester. LPH is the rarest subclassification of lymphocytic hypophysitis; it is typically found in males and has not previously been associated with pregnancy. Anterior and posterior pituitary deficits together with headaches should raise a high degree of suspicion regarding the possibility of LPH. The atypical magnetic resonance imaging finding of a heterogeneous pituitary mass additionally raised concern about pituitary apoplexy. Tissue from a transsphenoidal biopsy permitted diagnosis of lymphocytic hypophysitis. There was infiltration of the pituitary gland by small B and T lymphocytes. Resolution of the visual symptoms occurred after the biopsy and treatment with intravenous steroids.

    Abstract Painless low-grade right proptosis with 20/25 visual acuity developed slowly in a 49-year-old woman with a past history of breast cancer. Imaging studies disclosed an oval-to-round superotemporal mass in the right lacrimal fossa without bone erosion. Excisional biopsy revealed a pseudoencapsulated, bosselated tumor with a spindled, hypocellular, and heavily periodic acid Schiff-positive stroma constituted of abundant basement membrane material and collagen. Scattered lumens and focal cribriform cellular clusters were present in the peripheries of several of the lobules. Immunohistochemistry showed epithelial membrane antigen+ and cytokeratin (CK) 7+ in many small luminal structures. The spindled cells were calponin+, CK5/6+, CK14+, and p63+, confirming their myoepithelial nature. The Ki67 proliferation index was 2-3%, and upregulation of nuclear p53, a tumor suppressor gene product which may be aberrantly overexpressed in malignancy, was observed in rare cells. Immunohistochemical probes for HMGA2 and PLAG1 oncoproteins, characteristic of pleomorphic adenoma, were stained intensely and less intensely, respectively. MYB and c-KIT (CD117) were negative, thereby strongly arguing against the diagnosis of adenoid cystic carcinoma. In atypical epithelial tumors of the lacrimal gland, genetic probes identifying distinctive gene translocations or their oncoprotein products complement traditional immunohistochemical biomarkers such as cytokeratins and other structural or secretory molecules. Characteristic genetic abnormalities demonstrated by immunohistochemistry for their upregulated protein products, or by in situ hybridization for translocations, are increasingly being relied on for diagnostic precision.

    Abstract Purpose: To investigate the immunohistochemical features of ocular adnexal pleomorphic adenoma and adenoid cystic carcinoma.
    Design: Retrospective clinicopathologic study.
    Methods: Clinical records and microscopic slides of 7 cases of each tumor type were reviewed. Immunohistochemical probes for Ki-67 and p53, and newer nuclear markers MYB for adenoid cystic carcinoma and PLAG1 for pleomorphic adenoma, were employed.
    Results: Pleomorphic adenomas were asymptomatic, whereas adenoid cystic carcinomas were painful. No pleomorphic adenomas recurred; 4 adenoid cystic carcinomas recurred, resulting in 3 deaths. Unusual histopathologic variants for which immunohistochemistry proved useful included a myoepithelioma, an atypical pleomorphic adenoma, tubular and solid/basaloid variants of adenoid cystic carcinoma, and a morphologically heterogeneous adenoid cystic carcinoma of a Wolfring gland. For the pleomorphic adenomas, the average Ki-67 proliferation index was 3.8%; p53 was weakly staining, with an average positivity of 18.5%; PLAG1 was strongly positive in all cases; MYB was negative in 5 cases and weakly focally positive in 2 cases. For the adenoid cystic carcinomas, the average Ki-67 proliferation index was 29.1%; p53 stained positively and strongly with an average of 39%; none stained positively for PLAG1; and 6 out of 7 were MYB positive.
    Conclusions: Between pleomorphic adenoma and adenoid cystic carcinoma, there was no overlap in Ki-67 positivity. Positivity for p53 showed overlap in only one lesion of each type. PLAG1 and MYB positivity were highly discriminating between pleomorphic adenoma and adenoid cystic carcinoma. Immunohistochemical analysis should be investigated further for its role in the evaluation of pleomorphic adenoma and adenoid cystic carcinoma.

    Abstract Purpose: To describe the use of a Boston type I keratoprosthesis as a secondary penetrating procedure to treat gelatinous drop-like corneal dystrophy (GDLD), with presentation of pathologic findings, genetic analysis, and discussion of other surgical options.
    Methods: A 43-year-old woman with GDLD in both eyes, best corrected visual acuity (BCVA) of counting fingers in both eyes, and recurrent corneal opacification following two penetrating keratoplasties presented for visual rehabilitation. A Boston type I keratoprosthesis was implanted in her left eye after extracapsular clear lens extraction.
    Results: The surgery was uneventful and one month after surgery, best corrected vision improved to 20/30, which has been maintained for a period of more than nine months. At the 12-month visit, her vision was noted to be diminished to 20/200 due to a retroprosthetic membrane and improved to 20/25 two weeks after a Yag capsulotomy. Histopathologic examination of the corneal specimen disclosed predominantly subepithelial amyloid deposition. Genetic analysis is presented.
    Conclusions: GDLD is a rare disorder of primary corneal amyloidosis. Recurrence of this condition following surgery is very common. Boston type I keratoprosthesis as a secondary procedure can be successful in restoring vision in affected patients.

    Abstract Purpose: Tumor necrosis factor (TNF)-α is upregulated in eyes following corneal alkali injury and contributes to corneal and also retinal damage. Prompt TNF-α inhibition by systemic infliximab ameliorates retinal damage and improves corneal wound healing. However, systemic administration of TNF-α inhibitors carries risk of significant complications, whereas topical eye-drop delivery is hindered by poor ocular bioavailability and the need for patient adherence. This study investigates the efficacy of subconjunctival delivery of TNF-α antibodies using a polymer-based drug delivery system (DDS).
    Methods: The drug delivery system was prepared using porous polydimethylsiloxane/polyvinyl alcohol composite fabrication and loaded with 85 μg of infliximab. Six Dutch-belted pigmented rabbits received ocular alkali burn with NaOH. Immediately after the burn, subconjunctival implantation of anti-TNF-α DDS was performed in three rabbits while another three received sham DDS (without antibody). Rabbits were followed with photography for 3 months.
    Results: After 3 months, the device was found to be well tolerated by the host and the eyes exhibited less corneal damage as compared to eyes implanted with a sham DDS without drug. The low dose treatment suppressed CD45 and TNF-α expression in the burned cornea and inhibited retinal ganglion cell apoptosis and optic nerve degeneration, as compared to the sham DDS treated eyes. Immunolocalization revealed drug penetration in the conjunctiva, cornea, iris, and choroid, with residual infliximab in the DDS 3 months after implantation.
    Conclusions: This reduced-risk biologic DDS improves corneal wound healing and provides retinal neuroprotection, and may be applicable not only to alkali burns but also to other inflammatory surgical procedures such as penetrating keratoplasty and keratoprosthesis implantation.

    Abstract A whitish-opalescent, mildly elevated superior tarsal conjunctival lesion measuring 3.0 mm in diameter caused a refractory corneal abrasion in a 54-year-old man. Complete local excision without entering the tarsus produced relief of symptoms. There has been no recurrence during 9 months of follow-up. Histopathologically, a unique keratinous cyst was delimited mostly by basaloid cells resembling the matrical cells in pilomatrixoma. There were no keratohyalin granules in the lining cells, which focally transformed in ghost cells. These histopathologic features are characteristic of trichilemmal keratinization, a heretofore undescribed metaplasia of the conjunctival epithelium.

    Abstract A 71-year-old woman had a whitish mass of the outer right lower eyelid with an eccentric pore plugged with keratin. Histopathologic evaluation disclosed an epidermoid cyst that opened widely to the surface and was filled with flaky keratin. The wall displayed a proliferation of rete ridge-type structures that projected in the surrounding dermis. The lesion was diagnosed as a dilated pore of Winer and has not recurred after simple excision.
