RESUMO
Hamartomas, a focal excess of normal tissue usually presenting as isolated masses, are rarely found in the head and neck region. The purpose of this report is to discuss a rare case of an intra-oral angioleiomyomatous hamartoma in a 14-year-old male who presented with a congenital nodule over the anterior palatal mucosa. The confirmatory diagnosis was done based on histopathology and immunohistochemistry using various markers. A brief review of the literature and clinical differential diagnoses are discussed, along with the clinical significance of hamartomas associated with syndromes. Hence, the identification of such hamartomas may lead to early diagnosis of associated syndromes in pediatric patients.

BACKGROUND: Angioleiomyoma is a benign soft-tissue tumor that arises from the smooth muscle cells in the tunica media of the blood vessels. Although the most common location for these neoplasms is the uterine wall, they can also originate from lower limbs. Altogether, these neoplasms account for 0.2% of all those located in the foot and ankle region. Signs and symptoms of foot angioleiomyoma can be a localized pain, swelling, and functional impairment. To date, only case reports and case series with small populations have been reported in the literature to describe the clinical picture of these neoplasms and the effectiveness of surgical treatment. In this study, we report our results of surgical treatment for angioleiomyomas of the foot. METHODS: Thirteen cases suffering from angioleiomyoma of the foot underwent surgical resection in our institution between January of 2017 and January of 2022. For each case, we recorded preoperative and postoperative symptoms, and their preoperative and postoperative functional status according to both Musculoskeletal Tumor Society Score (MSTS) and American Orthopedic Foot and Ankle Society Score (AOFAS). Eventual complications and local recurrence were reported. RESULTS: Each patient had at least mild pain before surgical treatment. The mean preoperative MSTS and AOFAS were 22.1 and 76.8, respectively. The mean tumor size was 17.7mm. Preoperatively, each patient underwent resection with wide margins. None had local recurrences or major complications at their latest follow-up. After surgery, the mean postoperative MSTS and AOFAS increased to 29.5 and 98.8, respectively. Each case had a marked increment of their functionality and a reduction of their pain after surgery. CONCLUSIONS: Our results suggest that surgical approach with tumor resection should be considered a safe and reliable treatment for foot angioleiomyomas in light of the extremely low risk of local recurrence and because of the good postoperative pain relief and functional restoration that can be obtained after the treatment.

We present a novel case of a malignant transformation of an extremity soft tissue angioleiomyoma to leiomyosarcoma in a man in his late 70s who presented with a painful and increasing lump on his anterior tibia. Initial imaging and biopsy showed a benign angioleiomyoma which was excised for symptomatic reasons. An analysis of the resulting specimen revealed a 50×42×15 mm smooth muscle neoplasm consistent with angioleiomyoma with a 22×11 mm entirely intralesional nodular component in keeping with a grade 1 leiomyosarcoma. The malignant constituent of the lesion was entirely encased in benign angioleiomyoma negating the need for further surgery. Systemic staging investigation revealed no evidence of metastatic disease spread final staging as per the eighth edition of the American Joint Committee on Cancer (AJCC) Staging T1N0M0 R0 Stage 1 a.

BACKGROUND: Angioleiomyomas are benign mesenchymal tumors usually located in the limbs, with anecdotal reports in the spine. We present an atypical case of an epidural spine angioleiomyoma presenting with compressive myelopathy symptoms. The diagnosis was suggested based on MRI findings, and subsequently confirmed histopathologically. RESULTS: This is the first known occurrence of pure spinal epidural angioleiomyoma as a source of compressive myelopathy. The imaging presentation, especially the 'dark reticular sign' on MRI, was crucial in suggesting the diagnosis despite the atypical location CONCLUSION: This report serves to raise awareness among clinicians and radiologists about including angioleiomyoma in differential diagnoses for spinal epidural lesions with indicative MRI features. The favorable outcome after surgical intervention underscores the necessity of swift and accurate diagnosis followed by appropriate treatment for such uncommon spinal tumors.

This case report describes 2 dogs, an Appenzeller Mountain dog and an Irish Wolfhound, with angioleiomyoma within the nasal cavity. Endoscopic surgical resection resulted in cure in both dogs. Macroscopically and on diagnostic imaging, tumor masses may appear malignant because of local turbinate destruction. This highlights the importance of histological examination before any recommendations are made to owners because tumors of the nasal cavity may be benign and surgery curative.

Angioleiomyoma is a rare benign soft tissue tumour arising from smooth muscle, representing <1% of upper limb soft tissue tumours. We report a 54-year-old male presenting with a progressively enlarging atraumatic lesion along the palmar side of the base of the ring and little finger. A biopsy was done to determine the diagnosis. Intraoperatively, the lump was found to be intimately related to the radial digital artery, it could not be excised en-bloc without transecting the radial digital artery of the little finger. Following excision, the ends of the digital artery were anastomosed. At 10-months follow-up, the hand was fully functional without any evidence of cold-intolerance or neurological deficit along the distribution of the digital nerve. We review the literature on angioleiomyoma and report careful resection of the tumour with digital artery transection and repair as a treatment option for angioleiomyoma of the digital artery. Level of Evidence: Level V (Therapeutic).

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.

BACKGROUND: Uterine angioleiomyoma is benign tumor that composed of smooth muscle cells and thick-walled vessels. It is a very rare condition reported to present as lower abdominal mass, accompanied by dysmenorrhea and hypermenorrhea. However, its clinical presentation is not known. CASE PRESENTATION: We report the case of a 44-year-old Japanese woman who developed severe anemia with disseminated intravascular coagulation without obvious external bleeding. The patient had a huge abdominal mass of over 20 cm in size, which was thought to be a uterine tumor. She received daily blood transfusions and her condition improved rapidly after she underwent hysterectomy. Pathological examination of the tumor revealed spindle-shaped cells with little atypia and mitosis, and numerous large vessels with smooth muscle and thrombus in the vessels. CONCLUSIONS: Uterine angioleiomyoma was identified as the cause of the coagulation abnormality. CCND2 and AR gene amplification was detected in the tumor. Uterine tumors that present with coagulopathy despite a clinical course suggestive of benign disease should undergo differential diagnosis for uterine angioleiomyoma.

Angioleiomyoma is a benign tumor, which arises from the smooth muscle. It comprises approximately 4.4% of all benign soft tissues' neoplasms and they are commonly located at the lower extremities. They are most frequently found in middle-aged women. Angioleiomyoma is usually presented as a painful solitary lesion in the subcutaneous tissue. Due to the lack of evidence in the literature, the aim of this current concepts review was to provide foot and ankle surgeons the most updated and useful information for diagnosis and management of foot or ankle's angioleiomyoma. The possible diagnosis of angioleiomyoma is rarely thought of before surgery. X-ray, US, MRI, aspiration, scintigraphy, CT and EMG make part of the diagnostic tools available and angioleiomyoma's main characteristics in each of the exams are detailed. Angioleiomyoma cannot be neglected as consequence of delay or mistreatment increases morbidity and the potential risk to malignant transformation.

BACKGROUND Primary hepatic angioleiomyoma is a rare mesenchymal tumor that is characterized by blood vessels and smooth muscle. Herein, we report an extremely rare case of primary hepatic angioleiomyoma and discuss the clinicopathological features. CASE REPORT A 60-year-old Mongolian man was diagnosed with a hepatic tumor in the second and third segments of screening in 2012. It had been under control by a physician for 10 years. The patient had discomfort and vague pain in the right side of the abdomen since April 2022. Hepatitis virus markers (hepatitis B and hepatitis C) were negative. Plain computed tomography revealed an 80-mm solitary liver lesion in the left lobe with well-defined margins and heterogeneous enhancement. A left hepatectomy was performed in May 2022. The cut surface of the tumor showed a grayish-white, elastic, hard mass with a diameter of 50×80 mm. Histological findings of the tumor revealed that it was clearly demarcated from the surrounding liver tissues with relatively clear boundaries showing thick, muscle-coated blood vessels with perivascular smooth muscle bundles. Immunohistochemical staining showed that the smooth muscle cells were strongly diffuse and positive for smooth muscle actin. CONCLUSIONS Clinically, primary hepatic angioleiomyoma should be distinguished from other types of liver tumors, especially liver cancer. In combination with our long-term observation and other case reports, we recommend general follow-up if the preoperative pathological diagnosis can be confirmed and the patient has no other symptoms.

Angioleiomyoma in the head and neck area is rarely observed. This report introduces 2 cases of angioleiomyoma discovered in the parotid gland, particularly with the superficial temporal artery (STA) as the feeding vessel. Each patient was evaluated preoperatively by clinical manifestation and computed tomography scan, but the difficulty was encountered due to nonspecific radiologic features of angioleiomyoa. Surgical intervention was performed for precise diagnosis and treatment. The tumors were fed from the STA, with the diagnosis of venous type parotid angioleiomyoma. To our knowledge, there have been only one previous report of angioleiomyoma of the parotid gland fed from STA in the literature. Once parotid tumor is discovered, although rare, the possibility of angioleiomyoma should be considered, and the authors recommend prompt surgical excision for accurate diagnosis and treatment.

INTRODUCTION: Primary intracranial angioleiomyoma (ALM) is quite rare and ALM of the adolescent is even rarer. To date, only three cases of adolescents have been reported. MATERIAL AND METHODS: We carefully introduced a new location of intracranial ALM in an adolescent. The clinical, pathological and imaging features of intracranial ALM were described in detail and published literature was reviewed. RESULTS: To our best knowledge, we presented the fourth primary intracranial ALM of adolescent and the first ALM of the right frontal cranial base with intracranial and extracranial communication. We not only summarize the generalities of ALM but also illustrate the difference between adult and adolescent ALM in the aspects of gender and age predominance, etiology, common location and pathologic subtype. CONCLUSIONS: We reported the first ALM of the right frontal cranial base with intracranial and extracranial communication of an adolescent with a good prognosis. We also summarize the generalities of ALM and illustrate the difference between adult and adolescent ALM. Future investigation of control study with large patient cohorts is needed for both adult and adolescent ALM to compare the difference between them.

Angioleiomyomas are smooth muscle masses originating from blood vessel tunica media. This is a rare tumor, comprising less than 1% of benign sinonasal cavity tumors. Failure to recognize and surgically excise nasal angioleiomyomas can result in lesion recurrence. We present 2 new cases of nasal septum angioleiomyoma at a single institution. Additionally, both cases underwent septal and nasal surgery. Due to the nonspecific clinical and imaging findings, a high index of suspicion is needed to diagnose nasal septum angioleiomyoma, often requiring histopathological verification. Preferred treatment is complete surgical excision. From our experience, concurrent corrective septal and sinus surgery can be completed with tumors less than 1.0 cm in size.

Epithelioid angioleiomyoma (EALM) is rare in the skin and subcutaneous tissues. To the best of our knowledge, only two previous cases of this tumor have been reported. We document here the case of an 83-year-old woman who underwent complete removal of a squamous cell carcinoma of the retromolar trigone and lymph node dissection of the neck. An incidental EALM was observed in the adipose tissue. The tumor formed a unilocular, poorly demarcated neoplasm measuring 0.3 cm, and showed cavernous angiomatous spaces with villiform growth of large epithelioid cells arranged in clusters. Besides the epithelioid cells of muscular origin, bundles of well-differentiated smooth muscle cells were observed. Epithelioid cells accounted for 70% of the total. The neoplasm originated in the wall of a medium-sized vein. Epithelioid and spindle cells were positive for alpha-smooth muscle actin, calponin, h-caldesmon, and muscle-specific actin. The endothelial cells lining the vascular spaces showed intense and diffuse positivity for CD31 and ERG. The main differential diagnosis includes metastatic carcinoma, melanoma, perivascular epithelioid cell neoplasm, myopericytoma, glomangiomyoma, epithelioid glomus tumor, and epithelioid leiomyosarcoma. This report expands the morphological spectrum of the EALM. Awareness of this uncommon morphologic variant of angioleiomyoma and the use of adequate techniques can avoid misdiagnosis.
