CONTEXT The purpose of this study was to conduct a quality improvement (QI), applied practical review of the American Joint Committee on Cancer (AJCC) 7th edition, Carcinoma of the Eyelid staging system. AJCC utilizes a primary tumor, lymph node, metastasis (pTNM) cancer staging approach. OBJECTIVE We wanted to determine if the AJCC pTNM carcinoma staging system identified patients with highl...

PURPOSE/METHODS We report the case of a 73-year-old white female suffering from Merkel cell carcinoma (MCC) of the eyelid with an evolution of two and half months. MCC is a cutaneous neuroendocrine malignant tumor arising from Merkel cells. These cells are common along the eyelid margin in between the eyelashes. It is infrequent but highly aggressive and with potential metastases. Immunohistoch...

INTRODUCTION Tumour and tumour-like lesions of the eyelids are more common in dogs than cats. In the feline, malignant tumours outnumber benign types, with eyelid neoplasms essentially arising from the haired skin. Based on 1 study, squamous cell carcinomas, fibrosarcomas and adenocarcinomas constitute 73.5 % of all feline eyelid tumours. Apocrine hidrocystomas in cats are rare, solitary and mo...

Backarcund: Merkel cell carcinoma is a highly malignant cutaneous neoplasm with a high rate of local recurrence and systemic metastasis. Ten percent of all Merkel cell carcinomas involve the periocular region. We present three pStiSfltS. Patients and Methods: Patient 1 (B.H.). 86-year-old male presenting with a painless reddish tumor involving two thirds of the right upper eyelid and a basal ce...

Abstract Cutaneous squamous cell carcinoma (cSCC) is a keratinocyte tumour with inherent metastatic potential. Approximately 4% of cSCCs metastasize locoregionally and/or distally. Mohs micrographic surgery (MMS) efficacious, cure rates in selected cases 95–99%. Diagnoses cSCC treated at St James’s Hospital between the years 2010 and 2019 were identified via histopathology reports. Clinicopatho...

Ultrasound imaging is not traditionally employed to evaluate eyelid lesions. Nevertheless, this technology permits the delineation of static and dynamic changes and could be useful in evaluating eyelid masses by providing additional information to clinicians for optimal surgical planning, especially in facilities where a computed tomography (CT) scan is not readily available. A 63-year-old woma...
