A rare case of a middle ear glomangioma

Glomus tumors are benign hyperplasia of glomus bodies, and they are rarely found in the head and neck. The middle ear is an exceptionally rare site for a true glomus tumor, and there are only three previously reported cases in this location. Glomus tumors are etiologically different than glomus tympanicum, which are paragangliomas of the middle ear that are often mistakenly referred to as “glomus tumors.” This is a common misconception due to the “glomus” misnomer. We report a case of a patient diagnosed with a middle ear glomangioma after initially presenting to our clinic with tinnitus and hearing loss. The mass was surgically removed through a transcanal approach with carbon dioxide laser and sharp dissection. Literature review is also reported and revealed similar presentations in patients with middle ear glomangiomas.

Monoarthritis of the Elbow Revealing Osteoid Osteoma: A Case Report and Literature Review

Osteoid osteoma is a rare benign osteoblastic tumor that mainly occurs in the extra-articular segments of lower limb long bones. The elbow is an exceptional location for osteoid osteoma. The diagnosis is usually delayed since the elbow is a rare site for this tumor and unspecific clinical signs, such monoarthritis, may mimic other more common conditions. We report the case of a 16-year-old girl who presented with chronic monoarthritis of the elbow which was treated falsely as tuberculous arthritis and monoarticular rheumatoid involvement. The laboratory tests were negative. Computed tomography scan and magnetic resonance imaging showed the focal nidus at the coronoid process of the ulna with mild synovitis. The diagnosis of osteoid osteoma was not made until the disease had been progressing for eighteen months and the elbow had already become stiff. Arthroscopic excision of the lesion was performed, and histopathology of the nidus was consistent with osteoid osteoma. Since then, the patient has been pain-free with an improved elbow range of motion.

Rosette-forming glioneuronal tumours: two case reports and a review of the literature

Rosette-forming glioneuronal tumour (RGNT) is a rare central nervous system (CNS) neoplasm that typically arises in the fourth ventricle. It is even more uncommon to arise outside the midline. In this paper, we report 2 cases of RGNT: one located in the fourth ventricle (a typical site), and the other in the right cerebellar hemisphere (a rare site). Both cases were misdiagnosed on imaging, and the results were inconsistent with the pathological diagnosis. The aim of the article is to deepen medical practitioners’ understanding of RGNT by learning from these 2 cases, summarizing cases located in the cerebellar hemispheres and systematically reviewing RGNT.

A Giant Gastrointestinal Stromal Tumor of Duodenal Origin with Spontaneous Rupture Bleeding: A Case Report

BackgroundThe duodenum is a rare site of gastrointestinal stromal tumors (GISTs). The unique anatomical characteristics and rich blood supply of the duodenum make it difficult to treat duodenal GISTs in patients with bleeding.Case presentationHere we report a case of a 76-year-old female was hospitalized with a large GIST that originated in the duodenum. Imaging assessment suggested that the tumor could not be radically resected. However, the tumor was rupturing and bleeding, and therefore pancreaticoduodenectomy had to be performed. After receiving imatinib postoperatively, the patient has recovered during the 1 year after the operation.ConclusionThe results of this case suggest that pancreaticoduodenectomy may be a better choice for duodenal GISTs with rupture and bleeding.

Non-syndromic supernumerary premolar tooth buds at a rare site in the mandible

Hyperdontia involving the premolar teeth can be single or multiple or even related to a syndrome. These are frequently encountered in permanent dentition, but their occurrence has ranged between 0.09 to 0.64% in the general population. These are rarely found between the first and second premolars.

Tuberculous osteomyelitis of proximal fibula: An unusual presentation of tuberculosis

Tubercular involvement of the proximal fibula is rare. We present a case of tuberculosis of proximal fibula in an immunocompetent 22-year-old female. She was diagnosed clinically as a case of cellulitis. Radiological investigations, including magnetic resonance imaging revealed a destructive lesion in her right proximal fibula. Finally, by fine-needle aspiration cytology and GeneXpert polymerase chain reaction, a diagnosis of tuberculous osteomyelitis of proximal fibula was established. She was managed non-operatively with multidrug antitubercular chemotherapy. A high index of suspicion is required to make a diagnosis of musculoskeletal tuberculosis of such a rare site in the early stages.

A RARE CASE OF MATURE CYSTIC TERATOMA OF THE URINARY BLADDER

Introduction: Mature cystic teratomas or dermoid cysts are benign “tumors” which arise from more than one germ cell layer. These occur most commonly in the ovaries. Urinary bladder is an extremely rare site. Only few cases of urinary bladder dermoid cysts have been documented in the literature. Case report: We present a rare case in which a 29-year-old female patient presented with hematuria, passage of hairs in urine and painful micturition. Urinary bladder dermoid cyst along with vesicular calculus was diagnosed on imaging and cystoscopy and conrmed after surgery by histopathological examination. Conclusion: Bladder dermoids mimic bladder calculus and neoplastic mass lesion both clinically and radiologically. Correct diagnosis can be achieved by multimodality imaging, cystoscopy and conrmed on histopathology.

Tuberculosis tenosynovitis of the wrist: a rare case report

Tuberculosis (TB) is a common disease of the Asian continent and has a varied presentation. Involvement of the musculoskeletal system is uncommon and presents in 10% of extrapulmonary tuberculosis. The atypical sites of tuberculous infection are the spine (51%) pelvis (12%), hip and femur (10%), knee and tibia (10%), and ribs (7%), but involvement of the wrist is rare. Tuberculosis tenosynovitis is a rare site of extra-articular TB. Delayed diagnosis and hence treatment is because it mimics many other disease processes and as a result, complications are common. Median nerve compression leading to carpal tunnel syndrome may also occur in these patients. Here, we present a case of tuberculous tenosynovitis involving the wrist flexors and the radial and ulnar bursae treated with surgery.
