Angiolipoma, spindle cell lipoma, myelolipoma, chondrolipoma and myxolipoma are histological variants of lipomas arising from fat tissue. Although angiolipoma is the most common tumour in the trunk and forearm, it occurs infrequently in the head and neck region. In this report we present a case of angiolipoma occurring in the buccal mucosa of a 33-year-old man. The patient had noticed a painless mass in his buccal mucosa for 2 months. The surgically removed tumour, measuring 4 × 4 cm in diameter was histologically evaluated. The tumour was composed of proliferations of mature fat cells and connective tissue containing many small blood vessels, which were evenly distributed.
Adenoid cystic carcinoma is a malignant neoplasm most commonly originating in salivary glands of head and neck region. Here we present a case report of a 50 year old male who was diagnosed with adenoid cystic carcinoma of the right buccal mucosa. The peculiarity of the lesion and the approach we made is the key factor in the presentation.
A 36-year-old male patient presented with complaints of speaking and eating difficulties. He had a history of previous steroid injection to left TMJ a year ago for the management of internal derangement and from that time he slowly developed pain in the left TMJ associated with slight facial asymmetry [Table/ Fig-1]. Patient gave history of steroid injection (single dose) one year back due to lock jaw problem following which he developed pain and facial asymmetry. There was no history of trauma. Medical and family history was not significant. On clinical examination facial asymmetry was present and a localized swelling was present on left TMJ area which was diffuse, tender and hard in consistency. Tenderness elicited on TMJ area on opening and closing mouth and deviation of mandible on right side was present on mouth opening. Inter-incisal mouth opening was 30 mm. Radiographic examination revealed slight erosive lateral surface of left condyle and obliteration of left TMJ space on panoramic radiograph [Table/ Fig-2]. Clinic-radiographic correlation lead to following differential diagnosis: benign bone tumour of left condyle, fibrous ankylosis of left TMJ. As patient was not willing for advanced imaging, surgical exploration of joint was done where thick cartilaginous material was encountered at head of left condyle . Complete surgical excision of lesion was performed. On gross examination the specimen was measuring 1 × 0.5 cm in size, brownish white in color, firm in consistency. Postoperatively patient's mouth opening improved to 37mm.Microscopic examination revealed mono-nucleated, bi-nucleated and multi-nucleated cells having round to oval hyperchromatic nuclei within lacunae, suggestive of chondrocytes dispersed in hyaline ABStRACtOsteochondroma (OC) is one of the most common benign condylar tumours having both chondroma and osteoma. However, this tumour is most frequently found on the metaphyses of long bones and is unusual on the skull. When it affects the mandibular condyle, the cause could be due to trauma to the tempero mandibular joint (TMJ). Here, in this report we present a rare case of osteochondroma of left condyle region in a 36-year-old man. The patient had noticed pain in the left TMJ for six months. The lesion is surgically removed and histologically evaluated which composed of chondrocytes dispersed in hyaline matrix along with a rim of calcified bone at one end.matrix [Table/ Fig-4&5]. Areas of hemorrhage were also evident with minimal peripheral bony area. All these features confirmed the diagnosis of OC. Patient is on regular follow up. DISCUSSIoNThe World Health Organization defines the OC as a "cartilage-capped bony protrusion on the external surface of bone.'' It represents approximately 35% to 50% of all benign bone tumours and 8% to 15% of all primary bone tumours [1]. Though it is one of the most common benign tumours of the condyle, it is most frequently found on long bones and is uncommon on the skull [2]. OC of the mandibular condyle is thought to be a relatively rare lesion and o...
