Angioleiomyoma mimicking a swollen bursa on first metatarsophalangeal joint accompanying with hallux valgus deformity.

We present a case of a patient who underwent a modified scarf osteotomy and tumour excision based on a preoperative diagnosis of hallux valgus deformity and accompanying bursitis. Subsequent histopathological examination revealed that the tumour was an angioleiomyoma. While tumours around the first metatarsophalangeal (MTP) joint are typically associated with gouty nodules, infections, or swollen bursa (bursitis) in patients with hallux valgus deformity, the occurrence of soft tissue tumours in this area is rare. Moreover, angioleiomyoma is an even rarer form of soft tissue tumour and is seldom suspected prior to resection. To our knowledge, there have been no reports of angioleiomyoma arising in the first MTP joint. However, it is important to consider the possibility of an atypical tumour in cases where soft tissue masses are present, even in patients with hallux valgus deformity, and to perform at least imaging tests such as ultrasound and magnetic resonance imaging before surgery. This prospect should always be kept in mind.

Angioleiomyoma of the nasolacrimal duct: case report and literature review.

Angioleiomyomas are benign tumors composed of smooth muscle and vascular endothelium. While infrequent in overall prevalence, they are exceptionally rare in the head and neck. Herein, we describe the case of a 65-year-old female who was found to have an angioleiomyoma of the right nasolacrimal duct. Endoscopic excision of the lesion along with medial maxillectomy and dacryocystorhinostomy was performed without complication. The current report is one of the few reported cases of angioleiomyoma of the lacrimal drainage system.

Primary Intracranial Angioleiomyoma: A Case Report and Literature Review.

BACKGROUND: Angioleiomyoma is a benign soft tissue tumor that manifests as pain and is more common in the extremities. However, primary intracranial angioleiomyoma is an extremely rare entity that is poorly characterized clinically, radiologically, and histopathologically. We compiled and examined reported cases of intracranial angioleiomyoma to provide an up-to-date summary of the condition. A literature search was performed using PubMed with specific key terms. Selected case studies and case series were then compared, and statistical analyses were performed where appropriate. CASE DESCRIPTION: A 59-year-old woman presented with epileptic seizures and a 2-month history of progressive headache. Magnetic resonance imaging of the brain revealed a right temporal pole tumor near the right cavernous sinus. Gross total resection was performed. Histopathologic and immunohistochemical examination demonstrated an angioleiomyoma. No adjuvant radiation or chemotherapy was administered. Magnetic resonance imaging of the brain performed at 6-month follow-up showed no signs of recurrence. CONCLUSIONS: Primary intracranial angioleiomyoma is an exceedingly rare central nervous system tumor. The clinical and radiologic manifestations are nonspecific. The diagnosis depends on the histopathologic and immunohistochemical examination. For patients with clinical symptoms, surgical resection should be the first-choice treatment.

Angioleiomyoma of the inferior turbinate: a rare cause of isolated facial pain.

We present the case of a 33-year-old man with right-sided facial pain. Clinical examination revealed an isolated mass attached to the right inferior turbinate. This was confirmed with computed tomography. Excision was achieved endoscopically and histology revealed an angioleiomyoma. Full symptomatic relief was achieved after surgical excision. Less than 1% of angioleiomyoma lesions are found within the sinonasal cavity. We describe the first documented presentation of angioleiomyoma as a cause of isolated, unilateral facial pain; a very common presentation to the otorhinolaryngology clinic. We promote consideration of angioleiomyoma as a different diagnosis in the presence of facial pain and a unilateral sinonasal lesion. Endoscopic resection provides complete symptomatic resolution.

[Excision and tectonic covering of a vascular leiomyoma of the ciliary body with large anterior staphyloma using scleral patch graft]. / Exzision und tektonische Deckung eines vaskulären Leiomyoms des Ziliarkörpers mit großem anteriorem Staphylom mittels Sklerapatch.

Benign tumors of the ciliary body are rare and may potentially be confused with uveal melanoma in clinical routine. Clinical findings rarely allow for safe differentiation. Hence primary excisions are frequent. We report the case of a patient with a benign ciliary tumor, which was observed over a total of 13 years and eventually underwent a local tumor resection.

A giant superinfected uterine angioleiomyoma with distant septic metastases: an extremely rare presentation of a benign process and a systematic review of the literature.

PURPOSE: Uterine angioleiomyoma is a rare type of leiomyoma variant and there are few cases reported in the literature. The definitive diagnosis is usually obtained only after the histopathologic examination because there are no specific imaging criteria for this disease. The objective of this article is to review published cases about this clinical condition. METHODS: We report a case of giant angioleiomyoma superinfected by S. agalactiae with the development of latero-cervical distant metastasis in a premenopausal woman. Firstly, the case herein reported was orientated as an endometrial stroma sarcoma in the peri-operative histologic examination by frozen sections. It was treated with laparotomic total hysterectomy, bilateral salpingo-oophorectomy, inframesocolic omentectomy and pelvic and paraaortic lymph node dissection. Postoperative definitive anatomopathological analyses using a proper immunohistochemical panel revealed a case of uterine angioleiomyoma. We also review other case reports published about this clinical condition. RESULTS: We present the first case reported in the literature, in our knowledge, of a giant angioleiomyoma superinfected by S. agalactiae with the development of distant septic metastases. Immunohistochemistry permitted the definitive diagnosis of angioleiomyoma. Treatments previously reported are hysterectomy or tumor resection and any patient recurred. CONCLUSIONS: The definitive diagnosis is usually obtained after the definitive histopathologic examination since the use of immunohistochemical study has an important role in this regard. Complete surgical removal of the lesion is the treatment of choice, with no recurrent cases reported to date.

Angioleiomyoma as a rare cause of a painful subcutaneous nodule in the leg: a case report.

Angioleiomyomas are benign tumors originating in the vascular smooth muscles. The tumor typically presents as a painful, solitary, small subcutaneous nodule. Herein, we have described a case report of chronic leg pain due to angioleiomyoma. We outline the clinical, radiological and histopathological features of this rare diagnosis for a painful nodule of extremity. Although rare, angioleiomyoma should be included in the differential diagnosis of chronic leg pain.

Angioleiomyoma (Vascular Leiomyoma) Presenting as a Pseudoaneurysm of the Tibialis Posterior Artery.

Reported here is the case of a 55-year-old woman presenting to a podiatry clinic with a chief complaint of left heel and ankle pain, who ultimately underwent operative excision of an angioleiomyoma adjacent to the tibialis posterior artery at the level of the medial malleolus. Accompanying this case are images from three modalities through which the defining characteristics of an angioleiomyoma can be appreciated. This case advocates for the inclusion of angioleiomyoma in the preoperative differential diagnosis of a mass presenting as a pseudoaneurysm in the lower extremity, particularly among women in the fourth to sixth decades of life.

Tentorial Angioleiomyoma: A Rare Neurosurgical Entity. Case Report and Review of the Literature.

BACKGROUND: Angioleiomyoma (ALM) is a soft tissue neoplasm rarely described in the intracranial site. Because of their uncommon presentation, atypical neuroradiologic and pathologic features, ALMs are often misdiagnosed. CASE DESCRIPTION: We describe the neuroradiologic, clinical, and pathologic data of a 37-year-old male patient suffering from a tentorial ALM. He was admitted at our hospital because of a posterior cranial fossa mass. Magnetic resonance imaging (MRI) showed a left tentorial tumor, hypointense on T1-weighted sequences, with heterogeneous contrast enhancement after gadolinium injection ("salt-and-pepper" fashion) and slightly hyperintense signal on T2-weighted sequence. After surgery, pathological examination showed a tumor composed of several thick-walled blood vessels mixed with a population of deeply eosinophilic spindle-shaped smooth muscle cells arranged in bundles. Necrosis was absent. Neither cellular pleomorphism nor mitoses were detected. Immuno-histochemical analysis confirmed the smooth muscle phenotype of the spindle cell component: diffuse and strong positivity for alpha-smooth muscle actin, desmin, and h-caldesmon. Based on both morphologic and immunohistochemical findings, a diagnosis of primary intracranial ALM was rendered. CONCLUSIONS: We add to the literature the tenth case of this exceedingly rare tumor and submit that ALM should be suspected when a tentorial mass with a "flame-like" time-dependent pattern of contrast enhancement on MRI, a "salt-and-pepper" post-contrast appearance on MRI T1-weighted sequences, and a relation with large intracranial feeding vessels are present.

An uncommon cause of lower leg pain.

This article describes a patient with intense pain originating from a benign tumor on her leg. After 7 years of enduring this painful condition with no correct diagnosis, the patient finally underwent a biopsy and excision, which revealed the growth was an angioleiomyoma.

A Small Jejunal Angioleiomyoma Detected by Double-Balloon Enteroscopy: A Case Report.

BACKGROUND Angioleiomyoma in the small intestine is a rare cause of gastrointestinal bleeding. Only 7 cases of angioleiomyoma in the small intestine were reported in the English literature, with 4 of them causing gastrointestinal bleeding. The diagnosis of angioleiomyomas in the small intestine before surgery is difficult. CASE REPORT We report the case of a 42-year-old man with recurrent melena who underwent repeated esophagogastroduodenoscopy and colonoscopy, without positive finding. During a double-balloon enteroscopy, an elevated lesion with a diameter of 6 mm was found in the jejunum. The lesion was resected laparoscopically assisted with double-balloon enteroscpy. A microscopic examination showed fibric membrane of the mass and numerous vascular channels surrounded by proliferated smooth muscle. There were exudative fibrin and many thrombi formed by red blood cells. Immunohistochemistry was positive for SMA and CD34. A pathological diagnosis of jejunal angioleiomyoma with thrombus was established. During a 5-year follow-up, there was no further gastrointestinal bleeding. CONCLUSIONS The gastroenterologists should consider angioleiomyoma in the small intestine when assessing obscure gastrointestinal bleeding.

A preliminary study on classification and therapeutic strategies for spontaneous perirenal hemorrhage.

BACKGROUND: The aim of our study was to report our experience in the classification and therapeutic management strategies for spontaneous perirenal hemorrhage (SPH). METHODS: From September 2005 to April 2015, 20 patients with SPH were newly diagnosed in our hospital. Their clinical features, image findings, identification of underlying causes, and therapeutic management were retrospectively analyzed, and relevant literature was reviewed. In this study, patients were classified according to the degree of severity of the disease or emergency imaging diagnosis of underlying causes. On the basis of the former, patients were classified as critical and noncritical, and on the basis of the latter, patients were classified as renal cell carcinoma (RCC), undefined solid neoplasm, angioleiomyolipoma (AML), and unknown cause. RESULTS: In the acute stage, contrast-enhanced computed tomography (CT) was superior to ultrasonography for both diagnostic accuracy of SPH (p = 0.02) and etiology discovery power (p = 0.004). The results of contrast-enhanced magnetic resonance imaging (MRI) were identical to those of contrast-enhanced CT. We summarized a flowchart in the whole classification and therapeutic strategies of SPH. According to the imaging diagnosis of underlying causes, all the patients with undefined solid neoplasm or RCC underwent emergency operation. Patients with AML or unknown cause underwent selective arterial embolization (SAE) or conservative management according to the critical degree. Acute hemorrhage was controlled in 19 cases, of which 14 were cured by the operation and only one critical patient with severe shock died shortly despite rescue efforts. CONCLUSIONS: Contrast-enhanced CT or MRI is the first choice of imaging examination, which could not only accurately diagnose SPH but also detect the underlying causes. Choice of therapeutic strategies for SPH should vary according to the identification of critical patients and imaging diagnosis of underlying cause.

Pericytic tumors of the kidney-a clinicopathologic analysis of 17 cases.

The pericytic (perivascular myoid cell) family of tumors is a distinctive group of mesenchymal neoplasms encountered in superficial sites and only rarely seen in viscera. The pericytic family subtends a spectrum of lesions, namely, glomus tumors and variants; myopericytoma, including myofibroma; and angioleiomyoma. In light of the contemporary classification of pericytic lesions, we identified and reviewed 17 cases of renal pericytic tumors from the files of 6 referral centers. These tumors presented over an age range of 17 to 76 years (mean 46.7, median 53), with essentially equal male-female ratio. History of hypertension (available in 11 patients) was noted in 7 (64%), which persisted even after surgical resection, including in 2 younger patients (17 and 30 years). The tumors (1.7-11.0 cm) included glomus tumors (n=11); glomangiomyoma (n=1); glomus tumor with atypical features (n=1); and angioleiomyoma (n=1), as well as tumors showing features overlapping pericytic tumor subtypes (n=3). The histomorphology observed in these renal examples closely resembled that of their soft tissue counterparts, a subset with symplastic changes and atypical features, and pericytic immunophenotype. Despite large size and deep site, no progression was identified during a median of 7 months follow-up (1-62 months). In context of prior reported experience, our series identifies a wide morphologic spectrum, including lesions presenting composite morphologies. Taken with the experience of others, our series further corroborates that malignant behavior is rare, and that criteria associated with aggression among soft tissue pericytic tumors may not be predictive for those in the kidney.

Subcutaneous nasal angioleiomyoma: Case of a rare tumor and review of the literature.

We describe the case of a 46-year-old woman with a rare presentation of angioleiomyoma of the subcutaneous nasal tissue. The patient presented with pain and severe nasal obstruction. Her nasal deformity was sufficient to indicate an external rhinoplasty for both extirpation of the tumor and reconstruction of the defect with cartilage grafts. The procedure resulted in successful removal of the tumor and a satisfactory cosmetic outcome.
