Angiolymphoid Hyperplasia with Eosinophilia Involving the Occipital Artery: Case Report and Review of Literature.

Angiolymphoid Hyperplasia with Eosinophilia (ALHE) is an atypical vascular tumour occurring primarily in the head and neck area, which must be distinguished from Kimura's disease. The lesions can appear as single or multiple grouped intradermal papules or subcutaneous nodules. We report a rare case of ALHE in a 57-year-old female with a large lesion of three nodules involving the right occipital artery which had a long term evolution and we treated it by surgical excision. The definitive histopathological diagnosis was ALHE. Our case report is accompanied by a discussion of clinical, radiological and histological features. Surgical excision with free margins is the treatment of choice but, even though ALHE is considered a benign condition, recurrence is common.

Myositis ossificans of the masseter muscle: A rare location. Report of a case and review of literature.

BACKGROUND: Myositis Ossificans is a rare heterotopic bone formation within a muscle being the masticatory muscles exceptionally involved. In most cases there is a previous trauma, bearing in mind that there may be many other etiologies. CT scan and panoramic radiographs along with histological findings are essential diagnostic aids. CASE DESCIPTION: We report a rare case of MO of masseter muscle in 49 years-old woman after repetitive wisdom tooth infection with the discussion of clinical, radiological and histological features. CLINICAL IMPLICATIONS: MO is a rare disease of masticatory muscles being the masseter the most frequently affected. Wide surgical excision with free margins is the treatment of choice although close postoperative monitoring it's essential to avoid relapses. KEY WORDS: Myositis ossificans, myositis ossificans traumatica, masticatory muscles, masseter muscle, trauma.
