골연골종은원위 대퇴골, 근위 상완골, 근위 경골에 흔히 발생한다고 알려져 있으며 늑골에 발생한 골연골종은 상대적으로 드물게 보고되고 있다. 본 증례에서는 좌측 제6늑골 체부에 생긴 골연골종에 의한 우발성 점액낭과 그 주변에 생긴 연부조직 가성 종류가 발음성 견갑골 증후를 야기하여 관혈적 제거수술을 시행한 1례를 문헌 고찰과 함께 보고하고자 한다.

Inflammatory pseudotumor was originally described in the lung, but recently has been recognized to occur in various sites. A 56-year-old female was referred to our department with a painless swelling of the right midfacial area since 3 months ago. Clinical examination showed non-specific intraoral findings, but asymmetric facial appearance and numbness of the right midfacial area. Plain radiographs and CT images showed aggressive destruction and irregular thickening of the right maxillary sinus wall, increased antral opacification, and destruction of the zygomatic arch. A relatively well-defined soft tissue mass occupied the right maxillary sinus, nasal cavity, zygoma, and infraorbital region. The soft tissue mass showed mild enhancement on CT. Radiographically, this lesion presented a rapidly enlarging mass demonstrating aggressive behavior, mimicking a malignant tumor. Histopathologic examinations showed plasma cells and inflammatory cells in variable fibrotic tissues and demonstrated positive reactivity for vimentin. No malignent changes could be found.

The authors describe a rare case of inflammatory pseudotumor involving the clivus, where a soft tissue mass lesion, with extension into the prevertebral retropharyngeal space and the cavernous sinuses, was detected by CT and MRI. The mass resembled a malignant tumor or aggressive infectious lesion, and the final diagnosis of inflammatory pseudotumor was a diagnosis of exclusion, decided after histopathological examination.

Calcifying fibrous pseudotumors are rare soft-tissue lesions pathologically characterized by hyalinized collagen, psam-momatous or dystrophic calcification, and lympho-plasmacyte infiltration. They are clinically benign with an extremely low rate of recurrence and complete surgical resection is known to be the treatment of choice. We performed the resection of a calcifying fibrous pseudotumors in the anterior mediastinum without complications.

Inflammatory pseudotumor is characterized by the presence of a mass that may mimic malignancy and is composed of spindle cells mixed with variable amounts of extracellular collagen, lymphocytes, and plasma cells It is benign tumor commonly involves lung and orbit and rarely that occurs in the head and neck The cause and pathogenesis of inflammatory pseudotumor still remain controversial. Some bacterial infection or chronic irritation may have prompted some speculation that an initially reactive process can change into an overt neoplastic disease. It tends to affect children and young adults than old ages. We present a case of inflammatory pseudotumor involving the tongue base, in a 73-year-old patient with repeated oral bleeding that aggravated over a few days. Clinical examination showed angiomatous polyp like findings in oropharynx that easy bleeding tendency. CT images showed well defined soft tissue mass with focal enhancement. After surgery, tumor was finally diagnosed inflammatory pseudotumor by histopathologic examinations showed plasma cells and inflammatory cells in variable fibrotic tissues.

Focal myositis is a benign inflammatory pseudotumor of a skeletal muscle that clinically mimics a tumor of soft tissue, but the cause of which is obscure. I report here a case of multifocal recurrent nonpainful myositis found in a 68-year-old man who showed a subacute multifocal recurrent nonpainful inflammatory myopathy affecting discrete muscle groups with spontaneous remission and/or some medication.

Immunoglobulin G4 (IgG4)-related disease is an inflammatory condition characterized by IgG4 positive plasma cell infiltration. It can affect any organ in the body and mainly involves the pancreas, liver, biliary tracts, orbits, salivary glands and lymph nodes. It can manifest as an inflammatory pseudotumor. Pseudolymphoma as an inflammatory pseudotumor is a group of benign tumors that exhibit histological and clinical features suggestive of malignant lymphoma. Studies on IgG4-related disease are rarely reported, and no case of the disease that involved the maxillary bone and adjacent soft tissue, except for the skin, has been reported. Therefore, we report herein a case of pseudolymphomatous IgG4-related disease that involved the maxilla, with a literature review.

The Inflammatory myofibroblastic tumor (inflammatory pseudotumor) is a rarely occurring soft tissue lesion of unknown etiology. It can be of any location, but commonly it is found in lungs. It has been considered as a nonneoplastic reactive inflammatory lesion, but nowadays, confusion and dispute about its character is increasing due to its high recurrence rate and metastasis. We present a patient who had been diagnosed with an inflammatory pseudotumor in the right maxilla area, 1 year before visiting our hospital. After that, her pain and swelling did not resolved and she visit our hospital. On radiographic examination, aggressively infiltrative growth of the lesion with destruction of adjacent bony structure was noted. We found unusual aggressiveness of the inflammatory myofibroblastic tumor of the head and neck region. Because the typical behavior of the inflammatory myofibroblastic tumor is not defined yet, we recommend the surgical excision of the lesion and close follow-up.

Scapulothoracic bursitis, an uncommon lesion, has been reported to be a painful disorder of scapulothoracic articulation. The articulation may become inflamed secondary to trauma when overused because of sports or work that requires repetitive or constant movement of the scapula against the posterior chest wall. The bursitis usually appears as a growing mass at the scapulothoracic interface and is often confused with a soft tissue tumor. We report on a patient with scapulothoracic bursitis who underwent surgical excision.

Keloids are abnormally healed skin wounds that develop in the subpapillary layer of the dermis. They are a lesion with wide, raised and deep scars. They exceed the original dimensions of the wound and grow mounds upon mounds of collagen in a pseudotumor fashion. Their treatment may take several forms such as surgery, intralesional injection of steroid, compression, superficial irradiation, and combination therapy. However, absolute method is nothing until now. Recently, the cryosurgery shows relatively good effect in treatment, so we tried the clinical experience with cryosurgery in the treatment of keloids. Material and methods: During the past 2 years, we treated 20 individuals of the keloids with severe itching and pain. The age ranged from 5 to 45 years old. Only 6 cases were biopsied before and after cryotherapy. The cryosurgery set we used was Toitu model CR 201 $N_2O$ gas (tip temperature is $-80^{\circ}C$) and was applied directly on the lesion about 4 to 5 minutes with slight compression. After cryosurgery in keloids, the following results were obtained: 1. It is both quick and easy method. 2. It causes little or no pain and no loss of blood. 3. Integumentary normalization is rapid. The new scar tissue is smaller, and more elastic and soft. 4. The pain, itching and paresthesia commonly associated with keloid is usually disappeared. 5. Other treatment can be used after cryosurgery. 6. Histologic picture after cryosurgery is similar with the result of steroid injection. 7. The mechanism of the cryosurgery in keloids is the result of the direct tissue destroying action and cryoimmunologic reaction.
