A forehead hematoma as the initial clinical sign of lung cancer

Primary lung cancer commonly metastasizes to the brain, bones, liver, and adrenal glands. In some cases, bone metastasis serves as the first presenting sign of lung cancer with bone pain and headache, but it is not common. The incidence of skull metastasis in lung squamous cell carcinoma (SCC) is low, and there have been only a few cases of skull metastases serving as the first sign of malignancy with skull mass and epidural bleeding; however, no similar cases have been reported regarding that of hematoma. We report a case of an 84-year-old man who first presented with a simple forehead hematoma and was eventually diagnosed with SCC of the lung.

Extensive and aggressive growth of adenoid cysticcarcinoma in the lacrimal gland

Adenoid cystic carcinoma (ACC) in the lacrimal gland is a very rare disease with poor overall prognosis.Its primary treatment is surgical excision, including orbital exenteration and radical orbitectomy,which is combined with radiotherapy and chemotherapy. Age, histopathologic type, boneinvasion, and tumor extent are known factors that affect the prognosis of ACC. Furthermore, perineuralinvasion is highly associated with local tumor recurrence and tumor base invasion. Here,we report a rare case of ACC in the lacrimal gland with superior sagittal sinus invasion that repeatedlyrecurred after the surgical excision.

Intracranial abscess from facial cellulitis

Cellulitis, one of most common diseases of everyday life, is often overlooked for its significance. Although cellulitis does not cause or lead to serious problems usually, its possibility to cause life-threatening problem should be known. In present case, a patient who had received acupuncture treatment a week earlier presented to the clinic with symptoms of facial cellulitis. The disease resolved within few weeks under empirical antibiotic treatment but recurred after 3 months. Under close history review of the patient, we found out that the patient had received craniectomy 20 years ago. The patient had blunt headache with no other neurological symptoms that could suspect cranial infection, but considering the risk originating from the patient’s surgical history, brain computed tomography (CT) was taken. CT images revealed abscess formation in the subgaleal and epidural spaces. Craniotomy with abscess evacuation was done promptly. With additional antibiotic treatment postoperatively, the disease resolved, and the 1-month postoperative follow-up brain CT showed no signs of abscess formation.
