CASE DESCRIPTION A 15-year-old neutered male domestic shorthair cat was examined for treatment of a recurrent neoplastic mass in the left upper eyelid that had been excised 6 months earlier by the referring veterinarian. CLINICAL FINDINGS An apparently nonpainful firm cutaneous mass (approx 2 × 2 mm) was located on the lateral third of the left upper eyelid near the scar from the previous surgical excision. TREATMENT AND OUTCOME Approximately one-third of the left upper lip was used as a subdermal plexus (lip-to-lid) flap to cover the defect created by en bloc excision of the eyelid mass...

OBJECTIVES: To show the importance of frozen section-controlled excision to avoid the re-recurrence of recurrent basal cell carcinoma (BCC) of the eyelids. MATERIALS AND METHODS: Thirty-five cases who underwent eyelid tumor excision in different centers and were admitted to our clinic with recurrent eyelid tumors. Recurrent tumors were resected by excision 1-2 mm from the tumor's visible margin and sent to pathology for frozen section examination. Eyelid reconstructions with flap and graft were performed after confirming that the surgical margins were negative...

Dermatofibromas are most frequently encountered in women on the lower extremities, often after minor trauma. A 64-year-old woman developed a recurrent lesion of the right lower eyelid. 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...

PURPOSE: To describe the clinical presentation and treatment of a patient with a cutaneous pleomorphic adenoma of the eyelid. CASE REPORT: A 73-year-old male patient presented with a nodular mass on the lateral third of his right upper eyelid, which had slowly enlarged over 10 years. Radiologic features were of an extra-conical mass, with no invasion of adjacent structures. An excisional biopsy of the lesion was performed. The histopathological examination revealed a biphasic tumor, composed of tubules with a double layer of epithelial cells arranged in a chondromyxoid stroma...

BACKGROUND: Fluorescence confocal microscopy (FCM) is a recent imaging technique for the examination of surgical cutaneous specimens and has been suggested as a fast alternative to Mohs micrographic surgery. Up-to-date it has been used in the fluorescence mode and with vertical sections of the specimen margins. The aim of this study was to evaluate FCM in the reflectance mode and with a horizontal ("en face") scanning of the surgical specimen in a series of basal cell carcinoma (BCC) of the eyelid...

BACKGROUND: The facial dismasking flap (FDF) approach to operations on the deep skull base region consists of a coronal incision and a circumpalpebral incision. This approach provides a wide surgical field for extirpation of deep extended craniofacial tumors without leaving any undesirable scars on the face. Therefore, the FDF approach can provide satisfactory esthetical and functional results. Meanwhile, in some cases, especially in patients with a history of skull base surgery or orbital extension, patients are not fully satisfied even when the FDF approach is used...

REVIEW
Frederik Holm Svendsen, Steffen Heegaard
Lymphoma of the eyelid constitutes 5% of ocular adnexal lymphoma. In previously published cases, 56% of lymphomas of the eyelid are of B-cell origin and 44% are of T-cell origin. The most frequent B-cell lymphomas are extranodal marginal zone lymphoma (27 cases-14%) and diffuse large B-cell lymphoma (18 cases-9%). T-cell lymphomas are most frequently mycosis fungoides (25 cases-13%), extranodal natural killer/T-cell, nasal-type lymphoma (12 cases-6%), and primary cutaneous anaplastic large-cell lymphoma (12 cases-6%)...

Basal cell carcinomas are the most common malignant tumors of the eyelids. Patient history, clinical symptoms and signs, inspection, palpation and slit-lamp examination usually allow a working diagnosis; however, the clinical diagnosis requires histopathological confirmation and determination of the histopathological type. Squamous cell carcinomas, sebaceous gland carcinomas, melanomas and Merkel cell carcinomas can metastasize usually via the lymph vessels into the regional lymph nodes. Microscopically controlled excision of the primary tumor into healthy tissue is most commonly the first goal...

Sebaceous glands have high concentration over head and neck region. Despite high concentration, sebaceous cell adenoma and carcinomas are infrequent. Sebaceous cell carcinoma is an uncommon, cutaneous aggressive tumor arising from the sebaceous glands and seen almost exclusively on the eyelids (75%). It accounts for just 0.2-0.7% of all eyelid tumors in the USA and very few cases that have originated in areas other than the eyelids have been reported. A 67-year-old male presented with swelling (3 cm × 4 cm), on the right postauricular region, since about 1-month...

A 56-year-old man developed a 2 × 2 mm, yellow-orange painless, smooth-surfaced nodule in the middle third of his left upper eyelid. Microscopic evaluation disclosed a spindle cell tumor that was well circumscribed by a perineurium. The tumor cells manifested wavy, bland nuclei displaying comma-shaped and pointed ends. These cells were uniformly S100 positive. Immunohistochemical analysis further revealed an even dispersion of numerous dot-like neurofilaments diagnostic of an isolated intraneural neuroma...

Pituitary adenoma apoplexy is a well-known clinical syndrome induced by insulin infusion, cardiac surgery, trauma, and hypothalamic releasing factors. Pituitary apoplexy can cause secondary cerebral infarct and internal carotid artery occlusion. With blockade of tumor perfusion, apoplexy triggers a sudden onset of headache, visual impairment, cranial nerve palsy, disturbances of consciousness, eyelid ptosis, and hemiparesis. However, pituitary adenoma cells with high metabolic demand cannot survive with deficient blood supply and glucose concentrations...
