Conjunctival nevi are benign, heterogenous tumors that uncommonly arise from the lacrimal caruncle and plica semilunaris. We present a case of a patient diagnosed and managed for an unusual, pigmented nevus of the left caruncle involving the plica. An 84-year-old woman presented with a rapidly growing, pigmented lesion in her left nasal canthus. Examination demonstrated a raised, dark, pigmented area arising from the left caruncle and seeming to involve the plica semilunaris without scleral extension. The lesion was completely excised for histopathology, which confirmed the diagnosis of a compound nevus with pigment incontinence. Given the unfavorable anatomical position and prognostic significance in the case of malignancy, pigmented caruncular lesions should be thoroughly investigated with a low threshold for surgical removal.

UNASSIGNED: To report a case of coincidence of sebaceous gland hyperplasia and papilloma with detection of human papillomavirus-51 in the apical portion by in situ hybridization.
UNASSIGNED: A 75-year-old man noted discomfort at the inner canthus of his left eye when he blinked. A tumor of the lacrimal caruncle was identified and resected. The base of the tumor had a smooth surface and was whitish. In addition, a \"navel-like structure\" was seen, and the findings strongly suggested sebaceous gland hyperplasia of the lacrimal caruncle. The apical portion of the tumor was a papillomatous lesion. Histological examination of the resected tumor led to a diagnosis of sebaceous gland hyperplasia. Human papillomavirus-51 was detected in the apical portion by in situ hybridization. Based on these results, the final diagnosis was sebaceous gland hyperplasia with papilloma. No recurrence of either tumor has been observed up to 3 years postoperatively.
UNASSIGNED: This might be the first report of a case of coincidence of sebaceous gland hyperplasia and papilloma, even though the association between these two lesions was unclear, including which developed first.

We describe the case of a neurofibroma on the lacrimal caruncle of a female patient with neurofibromatosis type 1 (NF1). NF1 is an autosomal dominant genetic disease with a wide variety of clinical manifestations, one of the most common of which is neurofibroma. The lesion was removed surgically under general anesthesia and sent to histopathological analysis, which confirmed the clinical diagnosis of a neurofibroma.

An 84-year-old woman presented with a 3-month history of conjunctival chemosis in the left eye. At the first examination, the chemosis neighbored the lacrimal caruncle and was localized in the inferomedial region of the conjunctiva. During eyelid closure, only the left lacrimal caruncle was exposed. One month later, the chemosis further extended to the inferolateral region. We debulked the lacrimal caruncle to prevent the exposure of the caruncle. One month after the surgery, conjunctival chemosis had resolved completely. At the postoperative 6-month follow-up, the patient showed no recurrence of chemosis.

BACKGROUND: This is the third reported case of a steatocystoma simplex in the lacrimal caruncle.
METHODS: A 60-year-old male presented with a history of a slowly progressing mass in the right lacrimal caruncle since several years before his initial visit. At the first examination, a yellowish, relatively smooth surface mass was observed in the right lacrimal caruncle. The caruncular mass was completely removed under local anesthesia. The pathological findings of this mass were consistent with a steatocystoma. At the 6-month follow-up, there was no sign of recurrence or development of the steatocystoma or any other masses.
CONCLUSIONS: Although steatocystoma simplex rarely occurs in the lacrimal caruncle, it needs to be considered as a possible diagnosis for patients with a mass lesion in the caruncle.
