Orbital neoplasms

Histiocytic sarcoma (HS) is a rare and aggressive hematologic neoplasm characterized by the proliferation of malignant histiocytes. It infrequently presents with periorbital involvement. Here we present the first documented case of ocular adnexal histiocytic sarcoma composite with chronic lymphocytic leukemia/small lymphocytic lymphoma and provide compelling evidence for the transdifferentiation of chronic lymphocytic leukemia/small lymphocytic lymphoma to histiocytic sarcoma in an 80-year-old woman. Comprehending the clinicopathological characteristics of histiocytic sarcoma and various other histiocytic proliferations and neoplasms affecting orbital and ocular structures is imperative for ophthalmic surgeons and pathologists...

BACKGROUND: Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is a rare hematologic malignancy arising from precursor dendritic cells. It is a rare and challenging clinical presentation. For decades, there has been no treatment course for managing BPDCN and its overall prognosis is poor. METHODS AND RESULTS: We report a 27-year-old man who was admitted to the hospital due to an orbital tumor as the first symptom. Progressive enlargement of the orbital tumor was accompanied by multiple purple circular nodules on the body trunk...

BACKGROUND: The periocular skin is neoplasms-prone to various benign and malignant. Periocular malignancies are more aggressive and challenging to cure and repair than those in other skin areas. In recent decades, immunotherapy has significantly advanced oncology, allowing the autoimmune system to target and destroy malignant cells. Skin malignancies, especially periocular tumors, are particularly sensitive to immunotherapy. This technique has dramatically impacted the successful treatment of challenging tumors...

Schwannomas, also known as neurilemomas, are peripheral nerve sheath neoplasms. They can be sporadic or associated with genetic syndromes including neurofibromatosis type 2 (NF2). Schwannomas may lead to symptoms by exerting pressure on nearby structures, such as nerve and muscle fibers. In this study, we present the case of a 22-year-old female with a history of NF2 who, upon examination, presented with a visibly enlarged salmon-colored mass involving the left inferior rectus that she had since the age of 12 years...

Mucormycosis is an aggressive, fatal fungal infection. The fungal organisms are ubiquitous and easily affect immunocompromised patients. The main aim of this article is to emphasize over the knowledge of different diagnostic methods (diagnostic nasal endoscopy, ct/ contrast mri pns + orbit + brain, Wet KOH mount), the importance of practising an aggressive surgical resection, medical treatments (liposomal amphotericin B, amphotericin gel, tablet posaconazole, nasal douching, retrorbital amphotericin injection), suction cleaning and regular follow up of the patient after surgical management...

Endoscopic optic nerve decompression is a highly effective and reliable approach for patients with select cases of optic neuropathy. It reduces the hydrostatic pressure and helps in relieving the compressive forces within the intracanalicular portion of the optic nerve consequently preserving and arresting the deterioration of vision. The advantages of the endoscopic approach over other procedures include preservation of olfaction, quick recovery, lack of external scars and less morbidity. The objective of the study is to assess the surgical outcome of endoscopic optic nerve decompression in patients with traumatic and atraumatic optic neuropathy...

Rhinocerebralmucormycosis, is a progressive fungal invasion of a hard palate, paranasal sinuses, orbit, and brain. Post covid the huge number of mucor cases reported in our institute. To combat them a uniform assessment scale was needed as multiple healthcare workers were involved. Thus, a novel linear grading system on nasal endoscopy was developed for the early management of patients to prevent morbidity and mortality. A Prospective study of 650 patients in Epidemic duration from April to June 2021 in a tertiary health center, Central India...

Primary Mucinous eccrine carcinoma (MEC) is a rare malignant neoplasm of skin believed to arise from eccrine sweat gland commonly with periocular involvement. Here we report a case of 60-year male with a recurrence of unilateral nasomaxillary mass and epiphora. Imaging suggested nasolacrimal duct as probable site of origin. Histopathology and immunochemistry confirmed the diagnosis and managed surgically. This case report emphasizes the significance of including primary MEC in the differential diagnosis of nasomaxillary mass for its recurrence nature and histological similarity with metastasis from other viscera...

Peri-apical infection is a prevalent form of odontogenic infection, typically following the path of least resistance through cancellous bone towards the cortical plate. This infection begins as cellulitis and may progress to an abscess, sometimes involving various anatomically potential spaces. While frontal space infection is a rare complication of odontogenic infection spread, it can occur in conjunction with buccal space, sub-mental space, and orbital space involvement. In this report, we present the case of a 62-year-old man with a history of tooth pain and diabetes mellitus for the past decade...

OBJECTIVE: Eyebrow supraorbital craniotomy is a versatile keyhole technique for treating intracranial pathologies. The eyelid supraorbital approach, an alternative approach to an eyebrow supraorbital craniotomy, has not been widely adopted among most neurosurgeons. The purpose of this systematic review and meta-analysis was to perform a pooled analysis of the complications of eyebrow or eyelid approaches for the treatment of aneurysms, meningiomas, and orbital tumors. METHODS: A systematic review of the literature in the PubMed, Embase, and Cochrane Review databases was conducted for identifying relevant literature using keywords such as "supraorbital," "eyelid," "eyebrow," "tumor," and "aneurysm...

BACKGROUND: Numb cheek syndrome, a rare corollary of numb chin syndrome, is due to infra-orbital neuropathy. It can occur in association with an underlying malignancy, which can cause neuropathy by direct malignant nerve infiltration or via a paraneoplastic mechanism. Although numb cheek syndrome has been reported in association with a variety of cancers, it has previously not been reported in association with breast cancer. We report a case of left breast cancer presenting with left numb cheek syndrome...

INTRODUCTION: Multiple myeloma (MM), a plasma cell malignancy, is a systemic disease affecting various body organs. Plasmacytoma of bone and extramedullary disease (EMD) are presentations of MM. EMD is usually the sign of a more aggressive form of the disease. Herein, we report a patient with refractory MM presenting with extramedullary plasmacytoma in the superior oblique (SO) muscle. CASE PRESENTATION: A 51-year-old female presented complaining of gradual protrusion of the left eye and ocular pain from 20 days prior...

Lymphoma is the most common hematopoietic neoplasm in dogs. However, cases primarily involving the third eyelid are rarely reported in the species. The subtype most frequently described in this location is marginal zone lymphoma of the mucosa-associated lymphoid tissue, which has an indolent behavior. A 10-year-old intact female Poodle was presented with a 2-month history of a nodule in the left third eyelid for evaluation. This nodule was surgically excised; however, local recurrence was detected nineteen days postoperatively, with the formation of a mass that expanded and replaced the extraocular orbital tissues and infiltrated the eye...

BACKGROUND: Adult head and neck rhabdomyosarcoma (HNRMS) is an exceptionally rare malignancy, and there is a paucity of data and research dedicated to understanding its characteristics and management in adult populations. This study aimed to assess the outcomes and identify survival predictors in adult HNRMS. METHODS: We retrospectively evaluated 42 adult patients (> 16 years) with HNRMS who received radiotherapy (RT)-based treatment at our institute between 2008 and 2022...

Pediatric neoplastic extraocular soft-tissue lesions in the orbit are uncommon. Early multimodality imaging work-up and recognition of the key imaging features of these lesions allow narrowing of the differential diagnoses in order to direct timely management. In this paper, the authors present a multimodality approach to the imaging work-up of these lesions and highlight the use of ocular ultrasound as a first imaging modality where appropriate. We will discuss vascular neoplasms (congenital hemangioma, infantile hemangioma), optic nerve lesions (meningioma, optic nerve glioma), and other neoplastic lesions (plexiform neurofibroma, teratoma, chloroma, rhabdomyosarcoma, infantile fibrosarcoma, schwannoma)...

Orbital plasmacytomas are exceedingly rare neoplasms characterized by the proliferation of monoclonal plasma cells in the orbital soft tissues. Their presentation and clinical course can be diverse, making early diagnosis and management challenging. This case report sheds light on one such instance, emphasizing the diagnostic and therapeutic aspects of this uncommon condition. We present an 81-year-old patient with a prior diagnosis of multiple myeloma and bilateral orbital plasmacytomas, highlighting the importance of imaging in diagnosis and management...

A Gentleman in his 40s presented to us with left-sided hemifacial pain and nasal discharge for the last three days. He has been on immunosuppressive therapy for Wegener's Granulomatosis for over five years. Crusting was seen in the Left middle meatus upon clinical examination. Based on the post-covid status, steroid therapy, KOH mount, and radiologic imaging, a provisional diagnosis of Sinonasal mucormycosis was considered. He was posted for emergency debridement followed by Liposomal Amphotericin B and steroid therapy...
