Schwannoma is a slow-growing, well-demarcated, benign soft tissue tumor of the peripheral nerve sheath. It commonly develops in the head and neck region, usually in the parapharyngeal space. In this case, a 42-year-old woman visited the outpatient department to manage a painless mass on her left cheek. She had no history of concern and no neurological symptoms were observed. In the enhanced computed tomography scan, a 2.8 × 2.8 × 1.8 cm, heterogeneously enhanced tumor was detected in the left masseter muscle. A tumor resection under general anesthesia was planned. For the resection, a facelift incision was chosen; branches of the facial nerve were identified and retrogradely dissected. A well-marginated, yellowish, solid mass was found in the left masseter muscle. The mass was excised and given a histopathological diagnosis of schwannoma. A definite diagnosis of schwannoma, originating in the masseter muscle, is difficult to arrive at with radiographic findings alone; it is often misdiagnosed as intramuscular hemangioma. Histopathological examinations, including fine-needle aspiration or histological biopsy after surgery, are necessary. Using a facelift incision with retrograde facial nerve dissection, tumor resection in an intramasseteric lesion can be performed efficiently, without nerve damage, or leaving conspicuous scars on the face.

BACKGROUND: Infantile hemangioma (IH) is a common vascular tumor in pediatric patients, and is commonly treated with propranolol. We describe our experiences with dosage, response to treatment, and side effects in 23 IH patients treated with propranolol. METHODS: For this nonrandomized comparative cohort study, the authors enrolled 23 patients treated with propranolol. Photographs were taken before propranolol administration and at 3, 6, 9, and 12 months after treatment. Treatment responses were objectively analyzed with a computer program. RESULTS: There were three male and 20 female patients. Common tumor locations were the head and neck (13 cases, 56.5%), trunk (four cases, 17.4%), extremities (three cases, 13.0%), and combined locations (three cases, 13.0%). The response to propranolol was significantly lower in patients with two or more lesions than in patients with a single lesion in terms of both color fading (P < 0.001) and size reduction (P < 0.001). In male patients (42.2±3.9), the change in a-values, indicating coloration, was higher than in female patients (19.8 ±13.8)(P < 0.001). In patients who started treatment before 6 months after birth, the size reduction was greater than in their counterparts (62.3%; range, 3.0%–93.0% vs. 15.8%; range, 1.0%–79.0%; P < 0.001). CONCLUSIONS: Propranolol is an efficacious treatment with a good safety profile. In patients with a single lesion, the response to treatment was better in terms of color fading and size reduction. Furthermore, male patients responded better to propranolol treatment in terms of color fading than female patients, and starting treatment before 6 months after birth was more advantageous for size reduction.

Hemangiomas are the most common benign tumors in infancy, occurring most often on cutaneous and mucosal surfaces. Although less than 1% of hemangiomas occur in skeletal muscle, 15% of intramuscular hemangiomas arise in the head and neck musculature. Less than 10 cases of the sternocleidomastoid muscle have been reported in the English literatures. The masseter muscle is most commonly involved in the head and neck. Clinically, these tumors are present as distinct, localized, rubbery swelling. Neck computed tomography scan with enhancement may suggest a vascular mass within the muscle while angiography may detect feeding arteries in large intramuscular hemangiomas. The treatment of the hemangiomas is based on location, accessibility, depth of invasion, age, and cosmetic considerations. The optimal treatment is complete wide resection including the cuff of surrounding muscle. We report a case of hemangioma that occurred in the sternocleidomastoid muscle along with a with literature review.

Hemangioma is the most common benign tumor of a vascular origin, and is characterized by the abnormal proliferation of blood vessels. Intramuscular hemangioma (IMH) usually involves the skeletal muscles of the trunk or limbs, but rarely occurs in the head and neck region. This case report presents a patient with IMH showing multiple phleboliths in the buccal cheek. A 13-year-old boy was referred for the evaluation and management of painful swelling of the left cheek that had gradually increased in size over a 6 year duration. The examination revealed a palpable firm mass. Reddish-blue buccal mucosa color was observed with an aciniform shape. Preoperative magnetic resonance imaging (MRI) showed a vascular tumor in the left side adjacent to the buccinator and depressor orbicularis oris muscles. Surgical resection under general anesthesia was performed via the intraoral approach. The mass and phleboliths were extracted successfully. A histopathological examination confirmed the diagnosis of IMH. In conclusion, clinicians should be aware of the possibility of IMH in cases of a palpable mass with multiple nodules deep within the muscle in the buccal cheek. Among the several diagnostic tools, MRI provides essential information on the extent and surrounding anatomy of IMH.

Intramuscular hemangioma (IMH) is a rare vascular disease involving skeletal muscle, comprising only 0.8% of hemangiomas. About 10% to 15% of IMHs occur in the head and neck region, mostly involving the masseter muscle. IMH occurs mostly in childhood, but is often not found until unexpected enlargement, pain, or cosmetic asymmetry occurs in adulthood. Several non-surgical treatments including cryotherapy, sclerosant injection, and arterial ligature have been described, but complete surgical resection is the curative intervention. In this report, we present two rare cases of IMH. One IMH case in a 48-year-old male occurred in the masseter muscle feeding from the transverse facial artery. Embolization of the distal branch of the facial artery was first conducted, and then the buccal mass was removed surgically via the intraoral approach. A second IMH case in a 58-year-old female occurred in the orbicularis oris muscle feeding from the superior labial artery, and the mass was excised surgically without embolization.

Hemangiomas are relatively common in the head and neck region, but their occurrence in the temporal bone are extremely rare. The hemangioma of the external auditory canal (EAC) is a rare otologic entity as only 22 cases of hemangioma of the EAC have been reported worldwide. Here we report a patient presenting with pulsatile tinnitus, which turned out to be caused by capillary hemangioma arising from the posterior medial portion of external auditory canal touching the tympanic membrane. Surgical excision of the tumor was successful. The clinical manifestations and management of benign vascular lesions of the EAC are discussed with a review of literature.

OBJECTIVES: To provide an initial overview of the outcomes of different treatment modalities used for hemangiomas.
METHODS:
Design: Case Series
Setting: Tertiary National University Hospital
Participants: Records of 21 patients diagnosed with head and neck hemangiomas in the Philippine General Hospital Department of Otorhinolaryngology from 2009 to 2014 were reviewed.
RESULTS: Majority of the patients were female (61.9%) and in the pediatric age group (57.1%). Of the 21 patients, 6 underwent medical management, 13 had surgical management, 1 had both medical and surgical management and 1 opted to observe the lesion. All patients treated with propranolol observed a decrease in the size of the lesion. Seven out of the 13 patients had radiofrequency ablation; all had gross residual lesion. Six of the 13 underwent excision with complete excision being achieved in 5 of 6 cases.
CONCLUSION: Treatment response of patients in this series with hemangiomas of the head and neck to propranolol at a dose of 1 to 2 mg/kg/day may reflect international data. Outcomes analysis for radiofrequency ablation and surgical excision requires a longer duration of follow-up.

OBJECTIVE: To describe outcomes of oral propranolol therapy in a series of adult and pediatric patients diagnosed with benign capillary hemangioma of the head and neck.
METHODS:
Design: Prospective Case Series
Setting: Tertiary Government Teaching Hospital
Participants: Ten (10) patients representing all patients clinically diagnosed with benign capillary hemangioma of the head and neck enrolled in the study from 2012 to 2015.
RESULTS: Two (2) adults and eight (8) children were enrolled in the study. Although a decrease in lesion size was observed in half of the participants starting at three months, only one (1) attained complete resolution of the lesion-- a 12-year-old girl with hemangioma of the right parotid gland that attained clinical resolution of symptoms after four months of treatment. The remaining nine out of ten (9/10) participants did not attain complete clinical resolution; but there was a decrease in lesion size in four (4) of these participants. For the remaining five (5) participants, there was neither a decrease nor an increase in lesion size. Altogether, of the two adult participants, only one responded to therapy while only 4 out of 8 pediatric participants responded to therapy. There were no noticeable differences between adult and pediatric patients in terms of resolution and plateau. Aside from mild bradycardia expected with propranolol, no adverse reactions were observed during the course of treatment.
CONCLUSIONS: Although half of our participants responded to oral propranolol therapy whether these observations may be attributable to oral propranolol alone cannot be concluded.

Neck mass can be frequently encountered in pediatric patients. Most neck mass in pediatric patients are either inflammatory lesions or benign tumors but their differential diagnoses are not always easy. We must not forget the study results that a considerable portion of pediatric neck mass constitutes malignant tumors. Generally neck mass can be divided into inflammatory, developmental (congenital), and tumorous lesions. Developmental neck mass are generally thyroglossal duct cyst, branchial cleft cyst, dermoid cyst, vascular malformation, or hemangioma. Manifestations of inflammatory neck mass are reactive cervical lymphadenopathy, infectious lymphadenitis (viral or bacterial), mycobacterial cervical lymphadenopathy, or Kawasaki disease. The more uncommonly found pediatric malignant neck mass are lymphoma, rhabdomyosarcoma, or thyroid carcinoma. For the diagnosis of pediatric neck mass complete blood count, purified protein derivative test for tuberculosis, and measurement of titers for Epstein-Barr virus are required and in special cases, infectious diagnostic panels for cat-scratch disease, cytomegalovirus, human immunodeficiency virus, or toxoplasmosis may be needed. Ultrasonography is the most convenient and feasible diagnostic method in differentiating various neck mass. Computed tomography is performed when identifying the anatomical aspects of the neck mass or where deep neck infection or retropharyngeal abscess is suspected. Surgical management for congenital neck mass is recommended to prevent secondary infection or various complications following size increase. Most pediatric neck mass originate from bacterial lymphadenitis and antibacterial therapy is considered first line of conservative treatment. However if the neck mass is either over 2 cm in size without any evidence of inflammation, firm or fixed to surrounding tissue, accompanied by B symptoms, unresponsive to initial antibacterial therapy or over 4 weeks of conservative management, or considered keep growing for over 2 weeks, one must suspect the possibility of malignancy and must consult a head and neck specialist for further detailed evaluation.

Vascular malformations are the most common congenital and neonatal vascular anomalies in the head and neck region. The demand for simple and esthetic vascular malformation treatments have increased more recently. In this study, two patients that were diagnosed with venous malformations were treated with sodium tetradecyl sulfate as a sclerosing agent. Recurrence was not found one year after the surgery. This article gives a brief case report of sclerotherapy as an effective approach to treat vascular malformations in the oral cavity.
