“…In our case, the tumor demonstrated weak blood flow on CDUS. AAM is derived from myofibroblasts as a phenotypic variant of the basic fibroblast (12). Furthermore, there is no evidence of an anastomosing and arborizing vascular pattern in AAM (8,13).…”

“…Histologically, the tumor was characterized by spindle and stellate cells in a loose myxoid stroma with a prominent vascular component (2). Immunohistochemical staining of the tumor, particularly the reactivity for desmin, α-smooth muscle actin, muscle-specific actin, vimentin, CD-34, S-100 protein, estrogen and progestin receptors, is essential for diagnosis (12,15,16).…”

Abstract. In this study, we report a case of aggressive angiomyxoma (AAM) of the thigh in a 43-year-old female patient. Ultrasonography revealed a 6.1x3.7x5.3 cm solid mass in the right thigh with well-demarcated borders and a heterogeneous echotexture. Color Doppler ultrasonography (CDUS) revealed weak blood flow in the mass with peripheral and central avascularity. Computed tomography (CT) of the thigh revealed a homogeneous low-density mass under the spatium intermusculare of the quadriceps femoris. The mass was diagnosed as AAM by histopathological examination following complete excision around the adventitia of the tumor. At 18 months follow-up, there was no recurrence. In conclusion, this case is noteworthy as it involves AAM of the thigh, which is a rare tumor.

“…A retrovesical tumor is defined as "a tumor arising from retrovesical tissue excluding the pelvic organs such as rectum, bladder, prostate, seminal vesicle, vagina or uterus," and may or may not cause lower urinary tract symptoms [2]. This report discusses a rare case of AAM that caused lower urinary tract symptoms and presented itself as a retrovesical tumor on pelvic magnetic resonance imaging (MRI).…”

Aggressive Angiomyxoma as the Cause of Lower Urinary Tract Symptoms

Aggressive angiomyxoma (AAM) is a rare, benign tumor. It usually involves the connective tissue of the perineal regions in women of reproductive age. In this report, we present a case of AAM in a 66-year-old female, which presented itself as a retrovesical tumor on pelvic magnetic resonance imaging and caused lower urinary tract symptoms. CASE REPORTA 66-year-old female patient underwent abdominal pelvis ultrasonography (A-P sono) for a routine check. The A-P sono showed a mass between the urinary bladder and the vagina. For further evaluation of this mass, the patient visited the Department of Urology. She presented with frequency of urination and nocturia of three times per night. Her voiding diary showed that her functional bladder capacity was less than 200 ml. Upon physical examination, her abdomen was soft and movable and there was no tenderness. The mass was palpable through the vagina, and it was soft and round. The laboratory findings were within normal limits and her tumor markers, such as CA 19-9, AFP, and CEA, were within normal ranges. Transvaginal ultrasonography (TVUS) and pelvic MRI were performed.TVUS revealed a 5.1x4.7x3.4 cm sized homogeneous mass that was compressing the urinary bladder (Fig. 1A, B). On the pelvic MRI, the tumor was located in the retrovesical space and it was thought to be arising from the retrovesical tissue, such as the bladder, vagina, or uterus. However, we could not rule out that the tumor might have originated from the urethra. On the T1-weighted image, the tumor was of homogeneous and low intensity, similar to the image of the muscles. On the T2-weighted image, the mass was heterogeneous and of intermediate intensity (Fig. 1C, D). The tumor was thought to be a leiomyoma, a rhabdomyosarcoma, or a neurogenic tumor, as suggested by these MRI findings.In the operation field, the tumor was adhered to the posterior bladder wall. However, it was easily separated from the bladder wall and was resected en bloc. The resected tumor was 5.5x4x3 cm in size. Grossly, the tumor had a soft, smooth and elastic surface (Fig. 2). The cut surface showed whitish-yellow homogeneous lesions. Microscopically, the mass was made up of rather well-demarcated tumor tissues, which showed low cellularity of relatively uniform, small, satellite and spindly cells that were set in a loosely collagenous, myxoid matrix with scattered vessels of varying caliber. The tumor cells had scant, pale, eosinophilic cytoplasm with poorly defined borders and relatively bland nuclei with open chromatin and a single, small

Robotic assisted excision of retrovesical angiomyxoma in a male patient

Angiomyxoma is a rare tumour found predominantly in pelvis of young females. Less than 150 cases have been reported, more than 90% in females and only few cases in males. Its surgical excision is a big challenge and usually leads to recurrence due to incomplete excision. We report a case of retrovesical Angiomyxoma in an elderly male. The aim of this report is to highlight the rarity of this disease, especially in males, and robotic assisted excision as an evolving option of treatment.
