    Epithelial Inclusion Cyst in Conjunctival Melanoma
    (Sage Publications Inc, 2016) Esposito, Evangelina; Zoroquiain, Pablo; Mastromonaco, Christina; Morales, Melina C. [UNIFESP]; Belfort Neto, Rubens [UNIFESP]; Burnier, Miguel, Jr.
    Conjunctival melanoma is the second most common conjunctival malignancy. Its differential diagnosis with other conjunctival melanocytic neoplasms is inherently difficult. The presence of epithelial cysts is a useful feature in conjunctival tumors and favors a benign lesion. Herein 2 cases of conjunctival melanoma with cysts are presented. To the best of our knowledge, this is the first series of conjunctival melanoma with epithelial inclusion cysts. This series emphasizes the importance of considering several malignant features when reviewing conjunctival melanocytic lesions, as malignancy can exist even in the presence of epithelial inclusion cysts.

    Recurrent Primary Acquired Melanosis With Atypia Involving a Clear Corneal Phacoemulsification Wound
    (Lippincott Williams & Wilkins, 2011-01-01) Colby, Kathryn; Bhat, Pooja; Novais, Gustavo [UNIFESP]; Jakobiec, Frederick A.; Harvard Univ; Universidade Federal de São Paulo (UNIFESP)
    Purpose: To report a case of corneal primary acquired melanosis (PAM) with atypia after cataract surgery.Methods: Retrospective case report with literature review.Results: Excision of an elevated pigmented conjunctival lesion was performed at the time of cataract extraction by clear corneal phacoemulsification by an outside surgeon. Histopathologic examination revealed PAM with atypia. Three months after the initial surgery, recurrent melanosis involving the peripheral corneal epithelium was noted, with extension of pigment into the corneal stroma through the paracentesis site. Excision of the involved corneal epithelium and the adjacent conjunctiva was performed, and microscopically recurrent PAM with atypia was confirmed. Adjuvant cryotherapy was applied at the time of surgery, and topical mitomycin C was given postoperatively. Repeat biopsies revealed no remaining malignancy, and the intrastromal pigment has disappeared during 18 months of follow-up.Conclusion: We present this case to illustrate the importance of complete evaluation and treatment of potentially atypical melanocytic conjunctival lesions before proceeding with elective intraocular surgery.
