The term “sebaceous cyst” has fallen into disuse, the current term is an epidermoid cyst.
Other common synonyms include infundibular cyst, epidermal cyst, epidermal inclusion cyst, and epidermoid inclusion cyst.
These cysts are slow-growing masses that elevate the skin and often have a central punctum.
On radiology, they have round to oval structure, well-circumscribed, avascular mass; restricted diffusion is typical.
Removal may be accomplished by simple excision or incision.
The carotid body is the largest collection of paraganglia in the head and neck and is found on the medial aspect of the carotid bifurcation bilaterally. Carotid body tumors are rare neoplasms arising from the chemoreceptor cells of the carotid bulb. We report a case of carotid body tumor in a 42-year-old female, who presented with painless, pulsatile, gradually progressive lateral neck swelling. The diagnosis is suspected on the basis of history, clinical and radiological examination findings and a successful surgical excision of the tumor is performed. Histopathological examination confirms the diagnosis of carotid body tumor. We also present brief literature about carotid body tumors in terms of its clinical and imaging presentation, evaluation, and management.
Mature cystic teratoma is one of the most common tumors of the ovaries, testis, mediastinum, and retroperitoneum; however, secondary retroperitoneum lesions are rare entities in adults. We report a case of a 22-year-old female who was previously diagnosed with a mature teratoma of left ovarian was hospitalized due to dull abdominal pain in right hypochondria. Radiological evaluation revealed a mass in the right upper abdominal and flank region with an extension from the posterior aspect of the duodenum, composed of greasy and cystic elements. A tumor was resected through the Kocher's laparotomy and the pathology report confirmed the diagnosis of a mature cystic teratoma with no evidence of malignancy or immature components.
Left-sided appendicitis is usually caused by situs inversus totalis or midgut malrotation. Clinical and imaging diagnoses have been presented relatively fully in the literature. However, this is a rare condition, and each related case should be further reported to help the day-to-day clinician better investigate and understand. Therefore, in this paper, we present a case of left-sided acute appendicitis in an adult male patient with situs inversus totalis. In addition, we also discuss the laparoscopic technique of the left-sided appendectomy as it is technically more difficult because of the mirror nature of the anatomy.
Schwannomas are benign nerve sheath tumors that are generally encapsulated and commonly detected in the head, neck, and mediastinal regions. Schwannomas localizing in the pelvis are extremely rare and tend to be asymptomatic initially due to slow growth rate. Schwannomas may be misdiagnosed as urologic or gynecologic tumors. Pelvic schwannomas are typically solitary, large, and well-circumscribed masses in the retroperitoneum or presacral areas. Other imaging characteristics are cystic degeneration, repeated hemorrhages, and calcifications. Calcification patterns can be punctate, speckled, curvilinear, or along the walls of the masses. We report a young man with a pelvic schwannoma with typical imaging features.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
