Sclerosing pneumocytoma (SP) of the lung is a rare benign neoplasm. Here, we describe an unusual presentation of SP with a wax-and-wane pattern of growth in a 47-year-old woman. Tumor diameter decreased over a 3-year follow-up period and then increased on serial follow-up computed tomography scans. The mass showed high signal intensity on both T1- and T2-weighted chest magnetic resonance imaging (MRI) and early enhancement with a plateau on dynamic MRI. We speculate that intratumoral bleeding and resorption processes accounted for the changes in tumor size.

We report the dynamic contrast-enhanced CT and histopathologic findings of a rare case of recurrent pulmonary capillary hemangiomas. The findings consisted of peripheral nodular enhancement at the early arterial phase and a subsequent "central filling-in" enhancement pattern on the delayed scans, which was identical to the well-known enhancement pattern of hemangiomas of the liver. Although there was no evidence of histological malignancy, pulmonary capillary hemangiomas manifested as multiple nodular lesions and showed postoperative recurrence.

Glioma is the most malignant tumor in the brain, the origin of glioma is still unknown. Recently some papers indicated that glioma may be developed from cerebral cavernous malformation (CCM). We describe a man with a right temporal lobe CCM, after gamma-knife radiotherapy, the patient developed a low-grade astrocytoma in the area of the preexistent CCM. This case, together with other reports, may indicated an oncogenetic properties of CCM, and we proposed that CCM may be a pre-glioma lesion.

PURPOSE: To describe surgical outcomes for transconjunctival anterior orbitotomy for intraconal cavernous hemangiomas. METHODS: The medical records of 9 consecutive patients with intraconal cavernous hemangiomas who underwent surgical removal by transconjunctival anterior orbitotomy were retrospectively reviewed. The conjunctiva was incised and retracted with a traction suture. For large tumors, a rectus muscle was temporarily disinserted. Tenon's capsule was separated and the tumor was removed with a cryoprobe or clamp. Surgical outcomes, positions of the tumors, methods of approach, and intra- and post-operative complications were evaluated. RESULTS: The mean follow-up period was 33 +/- 6.8 months. No bony orbitotomy was used in this technique and the cosmetic results were very satisfactory. All tumors were removed intact. In 4 patients, tumors were extirpated with the aid of a cryoprobe. No patients had residual proptosis or limitation of ocular movement. No signs of recurrence were noted in any cases at 33 months follow-up. No serious or permanent complications were observed during or after the operation. CONCLUSIONS: Transconjunctival anterior orbitotomy is an important surgical procedure in the treatment of intraconal cavernous hemangiomas. It can produce an excellent result, even if the posterior border of the tumor abuts the orbital apex.

Intramuscular hemangioma, an infrequent but important cause of musculoskeletal pain, is often difficult to establish the diagnosis clinically. This report describes a case of a 32-yr-old woman who presented with severe left calf pain for 10 yr. Initial conservative treatments consisting of intramuscular electrical stimulation, herb medication, acupuncture, and intramuscular lidocaine injection under the diagnosis of myofascial pain syndrome in other facilities, failed to alleviate the symptoms. On physical examination, there was no motor weakness or sensory change. Conventional radiography of the leg revealed a soft tissue phlebolith. Conventional angiography study showed hemangioma. Intramuscular hemangioma within the soleus muscle was confirmed by magnetic resonance imaging. Following surgical excision of the hemangioma, the patient's symptom resolved completely. Intramuscular hemangioma is a rare cause of calf pain and should be considered in the differential diagnosis if a patient with muscle pain, particularly if associated with a soft tissue mass, fails to respond to conservative treatment.

Intracranial cavernous angiomas are benign vascular malformations and can be divided into intra-axial and extra-axial lesions. Extra-axial cavernous angiomas are relatively rare and usually arise in relation to the dura mater and mimick meningiomas. We report a case of cavernous angioma that occured in the falx cerebri of a 22-yr-old female patient with the special focus on neuroradiologic findings. This is the fourth case of cavernous angioma in the falx cerebri reported in the literature to our knowledge.

The primary esophageal lymphoma is extremely rare, and shows various morphologic characteristics. Only a single case of mucosa-associated lymphoid tissue (MALT) type lymphoma confined to the esophagus has been reported in the literature. A 61-yr-old man was referred to our hospital for evaluation of an esophageal submucosal tumor (SMT) that had been detected incidentally by endoscopy. He had a history of pulmonary tuberculosis with long-term anti-tuberculosis medication 15 yr before, and also had a history of syphilis, which had been treated one year before. He had been taking a synthetic thyroid hormones for the past 10 months because of an autoimmune thyroiditis. Endoscopy showed a longitudinal round and tubular shaped smooth elevated lesion, which was covered with intact mucosa and located at the mid to distal esophagus, 31 cm to 39 cm from the incisor teeth. Endoscopic ultrasonography (EUS) showed a huge longitudinal growing intermediate- to hypo-echoic mass located in the submucosal layer with internal small, various sized honeycomb-like anechoic lesions suggesting germinal centers. Subsequently, he underwent a surgery, which confirmed the mass as a primary esophageal low-grade B-cell lymphoma of MALT type.

Diffuse hepatic hemangiomatosis without extrahepatic lesions is extremely rare in adults. A case of diffuse hepatic hemangiomatosis involving right lobe in a 50-year-old woman was presented. The hemangiomatosis was demonstrated by ultrasonography, computerized tomography (CT) and magnetic resonance image (MRI), and was confirmed histopathologically. Although diffuse hepatic hemangiomatosis is a rare disease in adults, its diagnosis should be considered in patients with diffuse tumor growth in one or both hepatic lobes and distinguished from malignant tumors. The present case is the first documented case of diffuse hepatic hemangiomatosis in an adult in Korea.
