Smooth muscle neoplasms are more frequent in human immunodeficiency infected children than in HIV seropositive adults. Endobronchial leiomyoma is a rare benign tumor in HIV infected adult patients. Epstein-Barr virus (EBV) has been implicated in the pathogenesis of these tumors. Here we describe an adult patient with HIV infection with atelectasis of the left upper pulmonary lobe as the first c...

We report a case of multiple benign metastasizing leiomyoma (BML) lung nodules showing faint or non-avid uptake of F-18 fluorodeoxyglucose (FDG) (respective 1-hour early and 2-hour delayed maximum standardized uptake values; 1.3 or less and 1.2 or less) in a 50-year-old woman with a history of hysterectomy for uterine leiomyoma at the age of 38 years. When multiple lung nodules show faint or no...

Leiomyoma is a rare tumor arising from the uveal tract. Fundoscopically, it appears as a yellowish-white, elevated mass and cannot be readily distinguished from melanoma or other uveal tumors. Cross-sectional imaging may have an important role, particularly when the opaque ocular media or a vitreous hemorrhage precludes a clear ophthalmoscopic view. In this respect, radiologists should be aware...

Leiomyomas are benign tumors that originate from smooth muscle cells. Leiomyomas are well known to be the commonest neoplasm arising from the uterus but leiomyomas originating from the scrotum is a rare entity. They originate from the subcutaneous tissue or tunica dartos and can be solitary or multiple. We present a case of solitary scrotal leiomyoma in a 75 years old male who presented with a ...

Herein, we report on a well-characterized benign metastasizing leiomyoma, presented in an unusual site. Up to the knowledge of authors, so far, only 76 cases of benign metastasizing leiomyoma have been reported. The tumor presented as a retroperitoneal mass three years after a hysterectomy Performed for leiomyomatosis of the uterus with extensive areas of hyalinization. Histopathologic and immu...

Leiomyoma is one of the most commonly observed esophageal submucosal tumors, often appearing as a smooth-surfaced and semicircular protruded lesion. It sometimes grows toward the esophageal lumen and may be pedunculated in rare cases. We encountered a case of a pedunculated esophageal submucosal tumor diagnosed before treatment as a leiomyoma originating in the muscularis mucosae of a 68-year-o...

STUDY QUESTION Are interleukin-33 (IL-33) serum levels higher in women with uterine leiomyoma compared with controls without leiomyoma? SUMMARY ANSWER Serum IL-33 is elevated in women with uterine leiomyoma and correlated with features of uterine leiomyoma tumour burden, namely fibroid number, size and weight. WHAT IS KNOWN ALREADY Uterine leiomyomas are the most common benign tumours in pr...

A case of leiomyoma of the kidney is reported. A 57-year-old man with the chief complaint of right back pain was consulted to our hospital. Abdominal computed tomography (CT) demonstrated a right renal tumor. Right renal angiography revealed a hypovascular lesion. Under the diagnosis of right renal tumor, right radical nephrectomy was performed. Gross evaluation revealed a well encapsulated sol...

Leiomyomas are the most common pelvic tumors in women. About 20-30% of women older than 35 are affected. Rare conditions of leiomyomas have extrauterine locations. Myxoid degeneration is a rare type of leiomyoma degeneration. We report a case of solid-cystic myxoid leiomyoma in a 53-year-old woman complained of constipation, urinary hesitation, and malodorous vaginal discharge with palpable 17 ...

Hemangioblastoma is a rare benign tumor; common by found in the central nervous system, about 25% is associated with Von Hippel-Lindau (VHL) disease. Renal hemangioblastoma is extremely rare. The leiomyoma generally occurs in organs with abundant of smooth muscle such as uterus, gastrointestinal tract or subcutaneous soft tissue. It’s unusual to see it in the kidney, while the renal epithelioid...
