Angiomiofibroblastoma vulvoperineal, presentación de un caso / Vulvoperineal angiomyofibroblatoma, a case report

An angiomyofibroblastoma is a benign tumor that may present itself in the genital tract of a reproductive age woman. Despite it being a benign neoplasia, unable to be invasive, it can reach large sizes, producing discomfort, pain, and anatomical deformation. A late diagnosis may result in increased surgical difficulty for resection. The following is the clinical case of a woman with a vulvo-perineal tumor of 6 years of evolution, with a final diagnosis of angiomyofibroblastoma, in which complete resection of the lesion was achieved with good cosmetic results. The highlight of this tumor is its slow, silent, but progressive growth, leading to diagnoses that are often confused and late, with a consequent delay in treatment. Among the common differential diagnoses are the Bartholin gland cyst and the aggressive angiomyxoma.

El angiomiofibroblastoma es un tumor benigno que puede presentarse en el tracto genital de la mujer en edad reproductiva. A pesar de ser una neoplasia benigna, sin capacidad invasora, puede alcanzar grandes tamaños, produciendo molestia, dolor y alteración importante de la anatomía. Si el diagnóstico es tardío, aumenta la dificultad quirúrgica en su resección. A continuación, se presenta el caso clínico de una mujer con un tumor vulvoperineal de 6 años de evolución, con diagnóstico final de angiomiofibroblastoma, en el que se logró la resección completa de la lesión con un buen resultado estético. La importancia de este tumor está dada por su crecimiento lento, silencioso, pero progresivo, llevando a que su diagnóstico sea en muchas ocasiones confuso y tardío, con el consecuente retraso en el tratamiento. Dentro de los diagnósticos diferenciales comunes se encuentran el quiste de la glándula de Bartholino y el angiomixoma agresivo.

Angioleiomioma oral mimetizando um granuloma piogênico: relato de caso raro / Oral Angioleiomyoma mimetizing a pyogenic granuloma: A rare case report

Angioleiomioma (AL) é um tumor benigno de origem perivascular que raramente é observado na cavidade oral, principalmente em localizações como a gengiva. Devido sua apresentação clínica inespecífica, os ALs podem mimetizar outras lesões orais, como tumores benignos de glândulas salivares e lesões reacionais, como o granuloma piogênico. O presente artigo objetiva relatar um caso raro de AL localizado em gengiva, em uma paciente de 19 anos. Clinicamente, a lesão apresentava-se como um tumor assintomático, oval, pedunculado, bem definido, com superfície lisa, consistência fibrosa e cor eritematosa, semelhante a um granuloma piogênico, Uma biópsia excisional foi realizada e o fragmento foi encaminhado para análise histopatológica, que revelou uma proliferação vascular de diversos calibres, contendo paredes musculares espessas e proliferação muscular adjacente, além de infiltrado inflamatório, predominantemente crônico, hemácias extravasadas e área de ulceração, consistente com o diagnóstico de AL inflamado. A histopatologia desempenha um papel importante no diagnóstico final de lesões raras e com características clínicas inespecíficas. A excisão cirúrgica da lesão é o tratamento de escolha mais eficaz para os ALs orais. (AU)

Angioleiomyoma (AL) is a benign tumor of smooth muscle of perivascular origin that is rarely seen in the oral cavity, mainly in locations like the gingiva. Due to their nonspecific clinical presentation, ALs can mimic other oral lesions, such as benign salivary gland tumors and reactional lesions, as a pyogenic granuloma. We reported a case of an AL located in the gingiva in a 19-year-old female patient. In clinical terms, the lesion was presented as an asymptomatic, oval, pedunculated, well-defined nodule with a smooth surface, fibrous consistency and erythematous color, similar to a pyogenic granuloma. An excisional biopsy was performed and the fragment was sent for histopathological analysis that revealed a vascular proliferation of different calibers, containing thick muscle walls and adjacent muscle proliferation, in addition to an inflammatory infiltrate, predominantly chronic, extravasated red blood cells and an area of ulceration, consistent with the diagnosis of inflamed AL. The histopathology plays an important role in the final diagnosis of rare lesions and with nonspecific clinical characteristics. The surgical excision of the lesion is the most effective treatment of choice for oral ALs. (AU)

Angioleiomioma en cavidad oral «una neoplasia rara en un sitio poco común¼. Reporte de un caso y revisión de la literatura / Angioleiomyoma in the oral cavity «a rare neoplasm in an unusual site¼. Case report and literature review

El angioleiomioma (AL) es una neoplasia benigna, bien circunscrita y de crecimiento lento, que representa 5% de las neoplasias de tejidos blandos y cuya etiología es desconocida. Se origina del músculo liso, mayormente de las paredes de los vasos sanguíneos; su localización es más frecuente en extremidades, siendo raros en la región de cabeza y cuello, y más aún en cavidad bucal. Histológicamente la lesión se caracteriza por ser un nódulo bien encapsulado con proliferación de fascículos de músculo liso maduro alrededor de la luz de los vasos sanguíneos, cuyas células suelen ser positivas a marcadores de inmunohistoquímica como alfa actina de músculo liso, desmina, HHF35, miosina, calponina y H-caldesmon. El tratamiento actual es la escisión quirúrgica completa con una tasa de recurrencia prácticamente nula. El objetivo es resaltar la importancia del diagnóstico y el manejo correcto de las lesiones intraorales a través de la presentación de un caso clínico de un leiomioma vascular localizado en región nasolabial, además de hacer la revisión de la literatura correspondiente (AU)

The angioleiomyoma (AL) is a benign neoplasm, well circumscribed and slow growing, that represents 5% of the soft tissue neoplasms, whose etiology is unknown. It originates from smooth muscle, mostly from the walls of blood vessels; regarding its location, it more frequently appears in the extremities, being rare in the head and neck region, and even more so in the oral cavity. Histologically, the lesion is characterized by being a well encapsulated nodule with proliferation of mature smooth muscle bundles around the lumen of the blood vessels, whose cells are usually positive for immunohistochemical markers such as alpha smooth muscle actin, desmin, HHF35, myosin, calponin and H-caldesmon. The current treatment is complete surgical excision having zero recurrence rate. The objective of the following article is to educate on the importance of correct diagnosis and management of intraoral lesions through the presentation of a clinical case of a vascular leiomyoma located in the nasolabial region, in addition to reviewing the corresponding literature (AU)

Angioleiomioma uterino: a propósito de un caso / Uterine angioleiomyoma: report of clinical case

Resumen El angioleiomioma es un tumor benigno perivascular que raramente se localiza en el útero. Se expone el caso de un angioleiomioma de gran tamaño en una mujer de 30 años con sangrado menstrual abundante y masa abdominal palpable. La paciente fue sometida a miomectomía y diagnosticada de angioleiomioma por el estudio histológico. Ante síntomas persistentes, la angiomiomectomía o la histerectomía simple son eficaces.

Abstract Angioleiomyoma is a benign perivascular tumor that is rarely located in the uterus. This paper presents a case of a large angioleiomyoma in a 30-year-old woman with heavy menstrual bleeding and a palpable abdominal mass. The patient underwent myomectomy and was diagnosed with angioleiomyoma by histological examination. For persistent symptoms, angiomyomectomy or simple hysterectomy are effective.

Consideraciones del Leiomioma y su Variante Intraósea en Mandíbula, Algoritmo de Trabajo Según Análisis de Literatura / Considerations of Leiomyoma and its Intraosseous Variant in the Jaw, Working Algorithm According to Literature Analysis

RESUMEN: El Leiomioma es una neoplasia benigna originada en el tejido muscular liso por lo que puede manifestarse en cualquier región del cuerpo humano que contenga músculo liso, siendo el sitio más común el útero, la piel y en el tracto gastrointestinal. La escasa cantidad de tejido muscular liso en boca hace que su manifestación oral sea infrecuente, representando solo 0.06 % del total de este tipo de tumores. Los sitios más afectados suelen ser los labios, las mejillas, el paladar, la lengua y encías. Histológicamente se distinguen tres tipos: el Leiomioma Sólido, Angioleiomioma (Vascular) y Leiomioma Epitelioide (Leiomioblastoma). El origen de esta neoplasia en boca suele ser la túnica media de los vasos sanguíneos. El Leiomioma intraóseo suele ser aún menos frecuente, y con un diagnóstico diferencial complejo, con histopatología que en varias ocasiones no suele ser fácil de clasificar. Si bien es definida como un tumor benigno, su manifestación intraósea puede llegar a ser localmente agresiva y con un diagnóstico controversial, debiendo abordarse muchas veces como una neoplasia maligna. El objetivo de este artículo es presentar una revisión de la literatura de esta variante intraósea de Leiomioma situada en mandíbula, sus consideraciones clínicas y un algoritmo de tratamiento.

ABSTRACT: Leiomyoma is a benign neoplasm, the origin is the smooth muscle tissue that can be found in any area of the human body, which contains smooth muscle tissue. The most common regions it can be located, are the uterus, the skin and the gastrointestinal tract. The low quantity of muscle tissue in the mouth leads to infrequent oral manifestation, representing only 0.06 % of these tumors. The most affected regions are the lips, cheeks, palate, tongue and gums. The Histologic classification is: Solid Leiomyoma, Angioleiomyoma (vascular) and Epithelioid Leiomyoma (Leiomyoblastoma). The origin of this tumor in the mouth is the tunica media of the blood vessels. Nevertheless, and in spite of being defined as a benign tumor, it can be extremely aggressive, be subject to controversial diagnosis, and must often be treated as a malign neoplasm. The Intraosseous Leiomyoma is infrequent and presents a complicated differential diagnosis, with a histopathology that many times cannot be easily classified. The aim of this article is to present a review of intraosseous variant Leiomyoma in the mandible, the clinicians´ considerations and a treatment algorithm.

Ultrasonographic Findings of Subcutaneous Angioleiomyomas in the Extremities Based on Pathologic Subtypes

OBJECTIVE: The purpose of this study was to describe the ultrasonographic findings of angioleiomyoma based on pathological subtypes. MATERIALS AND METHODS: Thirty-nine patients with subcutaneous angioleiomyomas in the extremities were retrospectively reviewed by two radiologists and a pathologist. Sonographic images were analyzed to evaluate each tumor's anatomic location, size, shape, margin, heterogeneity, echogenicity, associated findings, and vascularity. RESULTS: Angioleiomyomas were divided into 3 subtypes: capillary (n = 16), venous (n = 22), and cavernous (n = 1). The one cavernous angioleiomyoma was a hypoechoic mass with rich vascularity. Hypoechogenicity was more frequently observed for venous tumors (77.3%) than for capillary tumors (43.8%), and isoechogenicity was more frequently observed for capillary tumors (56.2%) than for venous tumors (22.7%). Moderate vascularity was more frequently observed for venous tumors (59.1%) than for capillary tumors (12.5%), and little vascularity was more frequently observed for capillary tumors (62.5%) than for venous tumors (13.6%). The aforementioned findings including echogenicity (p = 0.034) and vascularity (p = 0.003) were statistically significant. CONCLUSION: Awareness of sonographic findings of angioleiomyomas based on pathologic subtypes could be helpful for diagnosing angioleiomyoma and could increase diagnostic accuracy for superficial soft-tissue masses in our practice.

Angioleiomyoma Originating from the Auricle / 대한이비인후과학회지

Angioleiomyoma is a benign tumor which arises from vascular smooth muscle. It originates primarily in the upper and lower extremities, but several isolated cases have been described. Although angioleiomyoma has a benign nature, there is a potential risk of malignant change and recurrence in case of incomplete resection. We acknowledge that venous type angioleiomyoma on the posterior surface of auricle has not been reported in the Korean literature. We report a rare case of 49-year-old male who had angioleiomyoma originating from the auricle along with a literature review.

Angioleiomyoma of the oral cavity: a case report and brief review of the literature

This study presents a case of an oral angioleiomyoma along with its clinical diagnostic approach and laboratory confirmation. The differential diagnosis, especially from angioleiomyosarcoma, is also included. A 51-year-old patient presented with a tumor-like lesion on his upper labial mucosa. The clinical examination revealed a benign lesion that was surgically removed. Histopathological and immunohistochemical examinations confirmed the diagnosis of an oral angioleiomyoma. The post-surgical period was uneventful. No recurrence had occurred after a year of follow-up surveillance. Oral angioleiomyoma is a very rarely occurring oral lesion. Clinically, it may mimic some benign lesions, including fibroma, pyogenic granuloma or minor salivary gland tumor. Surgical excision is the treatment of choice. Histological and immunohistochemical examination can confirm the diagnosis. The differential diagnosis is crucial to rule out angioleiomyosarcoma.

Successfully removed uterine angioleiomyoma by robot-assisted laparoscopic myomectomy

Angioleiomyoma is a rare type of leiomyoma variant and there are a few cases reported to date. Herein, we present a case of angioleiomyoma in a 36-year-old woman with lower abdominal pain, initially diagnosed by degenerated uterine leiomyoma. The transvaginal ultrasonogram showed an ovoid-shaped heterogeneously hyperechoic lesion in left cornual site of uterus and pelvic magnetic resonance image showed an about 5.1 cm sized heterogenous T2 intermediate high mass with poor enhancement. The patient underwent a robot-assisted laparoscopic myomectomy, and final histopathologic diagnosis revealed uterine angioleiomyoma. This case is the first case of angioleiomyoma resected by robotic surgery. The patient is on follow up for over 1 year and shows no evidence of recurrence until now.

A case report of angioleiomyoma of uterus

Angioleiomyoma (AL) is a very rare benign tumor that originates from smooth muscle cells and has thick walled vessels. It may be found throughout the body but more frequently occurs in the lower extremities and rarely develops in the head and other parts of the body. This paper presents a case report of giant AL detected in a 33-year-old woman who complained of severe anemia, menorrhagia, and palpable lower abdominal mass. The patient underwent myomectomy and was diagnosed with AL based on the pathological report of mass. The effective treatment for AL is either simple hysterectomy or angiomyomectomy depending on the patient's desire to preserve fertility and symptom.

Solitary Piloleiomyoma in the Scalp

Cutaneous leiomyomas can be classified into three types according to the site of origin: piloleiomyoma, angioleiomyoma, and dartoic (genital) leiomyoma. It might be expected that leiomyomas are commonly found on the scalp because there are many arrector pili muscles and vessels. However, leiomyomas are actually rarely reported in the scalp. Recently, we observed a case of cutaneous leiomyoma in the scalp and present our experience along with a literature review.

A Rare Case of Angioleiomyoma Arising in the Subglottic Area to Upper Trachea of a Patient with Underlying Asthma

Angioleiomyoma is a rare disease that is histologically characterized by smooth muscle cells arranged around vascular spaces. Although angioleiomyomas occur rarely in the head and neck region, they can cause various symptoms according the site involved. Here, we present a 44-year-old male patient with a 15-year history of asthma, who presented with recent onset of chest discomfort, globus sensation and throat pain. Medication was not effective in relieving his symptoms, and further evaluation revealed a polypoid ovoid mass, almost obstructing the airway at the border of the larynx and upper trachea on chest computed tomography. The mass was completely resected via a rigid bronchoscopy procedure. Histopathologic examination revealed that the excised mass was angioleiomyoma, which was immunohistochemically positive for smooth muscle actin and negative for desmin.

Sinonasal angioleiomyoma

Background: Angioleiomyoma of the nasal cavity is an extremely rare benign neoplasm. It usually occurs in the lower extremities. Up to date, only few cases of angioleiomyoma have been reported. First case of angioleiomyoma of nasal cavity was reported in 1966. We report a rare case of angioleiomyoma arising from the right maxillary sinus. Case Report: A 43-year-old lady presented with recurrent epistaxis and right nasal obstruction for two months duration. Clinical examination revealed a huge right nasal mass obstructing the right nasal cavity. The tumour was excised completely via endoscopic endonasal surgical approach. Histopathological examination confirmed the tumour is sinonasal angioleiomyoma. Postoperatively, she recovered well without any recurrence after a year of followup. Conclusion: This tumour has an excellent prognosis and recurrence is extremely rare if excised completely.

Angioleiomyoma of the gingiva: a report of two cases

Leiomyoma is a type of benign smooth muscle neoplasm that is a common neoplasm of the uterus and gastrointestinal tract but rarely affects the head and neck region and is especially unlikely to affect the oral cavity. The diagnosis of leiomyoma is mainly determined by histopathological studies due to variation in its clinical appearance and symptoms. In the present paper we report two rare cases of gingival angioleiomyoma in the posterior maxilla and mandible. After total excision, hematoxylin-eosin and smooth muscle actin staining confirmed the diagnosis of angioleimyoma.
