Basal cell carcinoma of the caruncle
ABSTRACT An 82-year-old white man presented with a 2- to 3-month history of a lesion in his left medial canthal region. Surgical excision of the lesion was performed, and histopathology showed a nodular basal cell carcinoma of the caruncle. Because of incomplete surgical margins after the initial excision, a second excision was performed, followed by a course of adjuvant radiotherapy. No tumor recurrence was detected in the caruncle after 6 months of follow-up.
Conference Paper: Analysis of rectangle dielectric antenna in time-domain[Show abstract] [Hide abstract]
ABSTRACT: This paper analyzes propagation characteristic of electromagnetic (EM) wave in rectangle dielectric waveguide by effective dielectric constant (EDC) method. The relationship between phase velocity and dielectric rod size is shown. This paper also discusses the feasibility of rectangle dielectric antenna used in time-domain and presents how to choose antenna's parameter and size. At the end of this paper some simulations are made by finite difference time domain (FD-TD) method. The influence of antenna's size, length and taper on the propagation and radiation characteristic is analyzed. The result shows that rectangle dielectric antenna is likely to be used in time-domain.Antennas, Propagation and EM Theory, 2003. Proceedings. 2003 6th International SYmposium on; 01/2003

ABSTRACT: Lesions of the caruncle are uncommon. On account of the histological composition of the caruncle, which includes, in addition to conjunctiva, hair follicles, sebaceous glands, sweat glands, and accessory lacrimal tissue, the caruncle may develop lesions that may be similar to those found in the skin, conjunctiva, or lacrimal gland. Clinical preoperative diagnosis is very difficult and reached only in about half of the cases. The vast majority of lesions of the caruncle are benign, mainly nevi. Reported malignant lesions are very rare but can be potentially fatal. Although malignancy is clinically overestimated, any suspected malignant lesion should be excised and examined histopathologically by an experienced pathologist. This study presents the clinical and histological data of 42 consecutive caruncular lesions processed at our laboratory and reviews previously reported cases of caruncular lesions.Eye (London, England) 11/2008; 23(5):1004-18.

ABSTRACT: Aim: The clinical and histopathological characteristics of a patient with a primary basal cell carcinoma (BCC) of the right caruncle without seeding of the tumor to the conjunctiva are described. Primary basal cell carcinoma of the caruncle is an extremely rare but distinct entity. Case Report: A 24-year-old female presented with a lesion of the medial caruncle of the right eye. Clinical examination revealed a 5×2 mm, oval-shaped, brown coloured, lesion without local skin involvement. No associated cutaneous lesion was present. The tumour was completely excised. One year later, no evidence of recurrence has been noticed. This case describes a primary BCC of the right caruncle without seeding to the conjunctiva. It represents the first case of right caruncle BCC documented in photographs.In vivo (Athens, Greece) 10/2013; 27(4):535-539. DOI:10.1097/IOP.0b013e31829bb48c · 1.15 Impact Factor
