Carcinogenesis has a multifactorial etiology, and the underlying molecular pathogenesis is still not entirely understood, especially for eye cancers. Primary malignant intraocular neoplasms are relatively rare, but delayed detection and inappropriate management contribute to poor outcomes. Conventional treatment, such as orbital exenteration, chemotherapy, or radiotherapy, alone results in high mortality for many of these malignancies. Recent sequential multimodal therapy with a combination of high-dose chemotherapy, followed by appropriate surgery, radiotherapy, and additional adjuvant chemotherapy has helped dramatically improve management...

Xeroderma pigmentosum (XP) is an autosomal recessive disorder associated with multiple oculocutaneous manifestations.We discuss a unique case of XP having bilateral ocular surface squamous neoplasia (OSSN) and periocular basal cell carcinoma. In the right eye, a large OSSN mass involving the ocular surface extensively along with intraocular invasion was noted, whereas in the left eye, the tumour mass was involving the limbus, and extending up to three clock hours. Because of extensive disease in the right eye, orbital exenteration was performed, and for the left eye, a wide excision of the mass with triple freeze thaw cryo application to the margins followed by amniotic membrane grafting was done...

Extravascular migratory metastasis (EVMM), also known as pericytic mimicry or angiotropism, is a mechanism of angiocentric tumor spread that has been investigated mainly in cutaneous malignant melanoma where it has been associated with an increased risk of metastasis. In EVMM, the tumor cells spread along the external (ablumenal) aspect of vessels without breaching the endothelium, a process that is therefore distinct from the more widely recognized intraluminal invasion. Although EVMM has also been reported in a limited range of other tumor types, to our knowledge it has not been described in squamous cell carcinoma (SCC)...

BACKGROUND: Recurrent cervical cancer with the pelvic side wall invasion has a deleterious effect on prognosis if there is no alternative method to achieve local tumor control [1, 2]. For the surgical treatment, super-radical hysterectomy has been introduced by Ryukichi Mibayashi in 1941 [3, 4]. However, its feasibility and safety is still on debate because of a lack of reproducibility and high level of surgical techniques. Thus, we showed the surgical procedure of super-radical hysterectomy for recurrent cervical cancer...

We report a case of inflammatory pseudotumor of the ureter. An 81-year-old man who had an operation of pelvic exenteration with ileal conduit presented with right flank pain. Computed tomography revealed a 16 mm mass of the right ureter with right hydronephrosis and renal atrophy. The mass increased in size during follow up. Right nephroureterectomy was performed with suspicion of ureteral cancer. Histopathological finding showed an inflammatory pseudotumor. No obvious recurrence has been observed for 33 months after the surgery...

BACKGROUND: Orbital exenteration is a radical surgical procedure resulting in deformity. It involves removal of the globe, optic nerve, extra-ocular muscles, orbital fat, lacrimal gland, and peri-osteum. Sino-orbital fistula (SOF) formation is a common documented post-operative complication, usually connecting the orbit and the ethmoid sinus. SOFs can cause leaks of serous fluid, and act as an entry site for pathogens into the orbit leading to socket infection and breakdown. METHODS: This retrospective study analyzed exenterations performed over a 22-year period (1993-2015) at the National Ocular Oncology Service Centre for Scotland...

A 42-year-old woman presented with chronic history of left red eye for more than 12 months, treated with difference topical medication but without response. Ocular external examination demonstrated a firm palpable mass in the medial portion of the lower eyelid and slit-lamp evaluation of the lesion showed an ulcerated conjunctival nodule, keratin secretor. CT of the orbits revealed left-sided orbital mass located anteriorly, inferiorly and medially in the orbit, adjacent to the globe and orbit walls. Incisional biopsy of the lesion was consistent with invasive squamous cell carcinoma of the conjunctiva...
