Soft-tissue hemangiomas are a common neoplasm of the angiomatous lesion origin that appear chiefly during childhood and is responsible for approximately 7% of the benign tumors. They are the most common angiomatous lesions that primarily affect women more than men. Intramuscular cavernous hemangiomas are rare in the limbs (0.8% of all hemangiomas), and <20% are mainly found in the head-and-neck region. In general, it is more common in young adults who have suffered from any kind of trauma. The frequency of hemangiomas is higher in the masseter muscle, whereas in very few cases, it is also observed in the buccinator muscle. An 18-year-old male presented at the tertiary care hospital with swelling in the right elbow measuring 1 cm × 1 cm. The swelling seemed to be arising from the right brachioradialis muscle. A benign cyst above the muscle plane was determined on the ultrasound examination. Furthermore, the excision biopsy sample collected for the histopathological examination showed irregularly dilated blood vessels lined with walls of varying thickness within the muscular plane. Based on the microscopic findings, the diagnosis of intramuscular cavernous hemangioma was made. The intramuscular cavernous hemangioma is a rare entity that makes it difficult to diagnose even with radiological investigations.

| Introduction|| |
Abnormal proliferation of blood vessels termed hemangiomas makes up 7% of all benign tumors. Specifically, intramuscular hemangiomas, a rare but important cause of musculoskeletal pain, account for <0.8% of all hemangiomas. In general, hemangioma is characterized by increased endothelial cell turnover that commonly appears after birth, grows rapidly, and then involute over the years. Hemangiomas are divided into five categories, depending on the predominant histology type. These categories include capillary, cavernous, arteriovenous, venous, and mixed type. Out of these categories, capillary hemangiomas are considered the most common type. Even though the growth of new mass with chronic pain is common in most cases, muscle contracture may also present, with the lower extremity being the most common region of involvement., Calcified round soft tissue may be identified on X-ray, termed phleboliths, but the best choice of diagnostic procedure would be magnetic resonance imaging. Conservative management, systemic corticosteroids embolization, radiation, sclerotherapy, and surgery are some of the few treatment options currently used to treat symptomatic intramuscular hemangiomas. Nonoperative treatments may also decrease the symptoms as the malformation involutes; this includes activity modification, compression garments, extremity elevation, nonsteroidal anti-inflammatory drugs, and physical therapy. Therefore, surgical intervention is advisable in cases with rapid growth, experiencing intractable pain, risk of necrosis in the local skin, thrombocytopenia, cosmetic or functional impairment, along with speculation of malignancy.
| Case Report|| |
An 18-year-old male reported to us with a right elbow swelling for the past 1 year. The swelling was gradual in onset and presented with minimal pain. Pain is often exacerbated with the exercise of the involved muscle. There was no history of potential trauma and infection. Family history was also noncontributory. On examination, the swelling was 1 cm × 1 cm in size and appeared to be arising from the brachioradialis muscle. The swelling showed mild tenderness with soft to firm in consistency. A provisional diagnosis of fibroma was made. Ultrasonographic examination revealed benign cystic swelling, measuring 1 cm × 0.8 cm, into the muscle plane in the right elbow region with no significant vascularity within and around the lesion giving an impression of a benign lesion.
Fine-needle aspiration cytology (FNAC) was performed twice, which revealed only bloody aspirate confirmed under the microscope and was categorized as unsatisfactory for evaluation. Because of radiology and cytology limitations to provide a conclusive diagnosis, excisional biopsy for histopathological examination was advised. The excision was done under local anesthesia and sent for histopathological examination. The gross specimen showed a solitary soft-tissue mass, soft to firm, bluish-white in color, irregular in shape, and measuring 1 cm × 1 cm × 0.8 cm. Cut section was hemorrhagic. Histopathological examination of the prepared sections showed irregularly dilated blood vessels lined with walls of varying thickness within the muscular plane. Flattened endothelium lining the endothelium was seen [Figure 1] and [Figure 2]. On the comprehensive evaluation of the clinical features, radiology, and cytology, a definitive diagnosis of intramuscular cavernous hemangioma of the right brachioradialis muscle was made.

| Discussion|| |
Soft-tissue hemangiomas are common neoplasms of benign nature., Angiomatous lesions are the most common type, and they account for 7% of the benign tumors in the general population. Hemangiomas are the most frequently diagnosed in children as soft-tissue neoplasms. Women are more often affected than men. Pain is the main symptom in the majority of the cases, with the lower extremity being the most common region of involvement., Hemangioma is characterized by increased endothelial cell turnover that usually appears after birth, grows rapidly, and then involute over the years. Hemangiomas are divided into five categories, depending on the predominant type of histology. These categories include capillary, cavernous, arteriovenous, venous, and mixed type. Out of these categories, capillary hemangiomas are considered the most common type. They are usually found in the skin, subcutaneous tissue, or vertebral bodies during the first few years of life. Cavernous hemangiomas present with many dilated and congestive vessels with a flattened endothelium. Calcification is common. In the majority of the cases, surgical intervention is required. Arteriovenous hemangiomas present as an abnormal communication between arteries and veins, leading to a variable degree of shunting.
Intramuscular hemangiomas are very rare, accounting for <1% of all hemangiomas. The masseter muscle is the most frequent muscle, accounting for 5% of all intramuscular hemangioma. The first case of intramuscular cavernous hemangioma naming it as an “erectile tumor,” was reported by Liston in 1843. Intramuscular hemangiomas represent congenital vascular malformations developmentally and are considered hamartomatous lesions and thought to arise from abnormal embryonic rests. Another theory suggested their origin could be attributed to the growth of a latent hemangiomatous lesion resulting from trauma., Intramuscular hemangiomas are usually seen in the first three decades of life with no gender predilection. They present as a slow-growing mass without any signs and symptoms indicating its vascular nature. An absence of thrills, bruits, compressibility, pulsation, and overlying skin is also expected. Making a diagnosis of intramuscular hemangioma is quite challenging as they exhibit minimal signs on clinical examination. Even imaging techniques are not very useful and may show more extensive lesions than suspected., These lesions are slow-growing and rarely metastasize, with a more than 9% recurrence rate after surgical removal. Ultrasound is considered the first line of imaging for diagnosis showing high vascularity and abundant blood flow.,, However, in the present case, ultrasound did not show any features characteristic of the diagnosis. After that FNAC was performed to provide a cytological diagnosis. FNAC was attempted twice. On both the attempts, FNAC yielded only blood which was confirmed microscopically. Due to insufficient cellularity, FNAC smears were categorized as unsatisfactory. Discordance between clinical features, radiology, and cytology to confirm a diagnosis leads to excision biopsy and histopathological examination. Histopathology sections showed characteristic features with irregularly dilated blood vessels lined with walls of varying thickness within the muscular plan. After combining the clinical feature findings and microscopic findings, the final diagnosis of intramuscular cavernous hemangioma was made. On re-evaluation of FNAC smears, it was observed that the blood was indeed fresh blood from the hemangioma and correlated with the diagnosis.
| Conclusion|| |
The intramuscular cavernous hemangioma is rare, making it difficult to diagnose even with radiological investigations. However, a comprehensive evaluation of clinical features and pathological investigations aids in the diagnosis. Bloody aspirates in the FNAC in a proper clinical setting may point toward hemangioma diagnosis. Therefore, it should invariably be kept in the differential diagnosis of soft-tissue tumors.
