Intramuscular haemangioma is relatively rare and accounts for less than 1% of all haemangioma.
Most of these tumours occur in the trunk, arms and legs. Only 14% of all intramuscular haemangioma arise
from the head and neck region, with masseter muscle representing the most common site of involvement,
followed by the trapezius and sternocleidomastoid muscles. We present a case of a 60-year-old man with a
soft lump in the left cheek. Imaging of the neck showed irregular, dilated enhancing vessels seen in the left
masseter muscle suggestive of intramuscular haemangioma. Excisional biopsy was performed, and
histopathological findings confirmed the diagnosis.
Osteomas occur in all parts of the temporal bone, including the mastoid, squamous, middle
ear, styloid process, internal auditory canal and external auditory canal (EAC). The EAC has
been reported to be the most common site, followed by the mastoid and squamous parts.
Diagnosis is made based on history, clinical examination and radiological findings. Computed
tomography reveals a pedunculated hyperdense mass that usually arises from the
tympanosquamous suture. Surgical removal of EAC osteomas can be achieved using the
endaural or postauricular approaches. It can be performed with a drill or osteotome, either
endoscopically or by using microscopy. This report presents two patients with EAC osteomas
who underwent excision under microscopy using the endaural approach. Surgery is the gold
standard treatment, while close observation may be considered in asymptomatic patients.
