The extranodal nasal NK/T-cell lymphoma was formerly known as lethal midline granuloma due to its most common clinical pattern like a destructive midline facial tumor. It often spread to other extranodal sites, such as skin, soft tissue, testis, upper respiratory tract, and gastrointestinal tract etc. For this reason, the term of extranodal NK/T-cell lymphoma, nasal type is preferred. Its disease entity may have a prominent admixture of inflammatory cells and necrotic tissues, further causing difficulty in diagnosis. A 44-year-old man was visited to our clinic with complaints of dysphagia and odynophagia during six months. He underwent three times punch biopsies and then, two times incisional biopsies. Finally, He was diagnosed as extranodal NK/T-cell lymphoma, nasal type involving oropharynx and supraglottis. We report an extremely rare case of extranodal NK/T-cell lymphoma, nasal type occurred in oropharynx and supraglottis with a brief review of literature.

Although the typical CT findings of Pneumocystis jiroveci pneumonia (PJP) include diffuse or multifocal areas of ground-glass opacities in both lungs, it can also rarely manifest as multiple pulmonary nodules. We report a rare case of atypical PJP in an immunocompromised patient with multiple myeloma, presenting as widespread ground-glass opacities and multiple necrotic subpleural nodules in both lungs on CT, which proved to be granulomatous PJP on percutaneous transthoracic needle biopsy.

The seeds of 16 species from sect. Anthacantha and related taxa were examined using light and scanning electron microscopy to illucidate the boundary of the section and their relationship among species. Using six qualitative characters clustering analyses were conducted, and three types were recognized. Type I including species from sect. Anthacantha+sect. Meleuphorbia is characterized by the ovate shape, rounded at base and smooth along the ventral line. Type II including species from sect. Medusae+sect. Treisia-1 is squared in shape and are tuberculate. Tubercles are prominent along the ventral line. Type III (sect. Treisia-2 group) is mostly rounded, and as in type II, tubercles are prominent along the ventral line, but the unique crestae consisting of the grouping testa cells differed from the surface patterns of Types I and II. Based on the seed morphology, sects. Anthacantha and Meleuphorbia are closely related, which is well supported by the results from molecular and pollen morphological studies. Besides, sects. Treisia and Medusae are not closely related in terms of seed characters, and this is not consistent with the results of recent molecular studies.

The nodular hyperplasia of the thyroid is a common thyriod disease. Nodular hyperplasia does rarely progress to thyroid cancer. The differentiation of a nodular hyperplasia from a neoplasm may be simple or difficult, both clinically and anatomically. The papillary carcinoma of the thyroid is the most common type of thyroid malignancies. There were few studies about cytogenetic observation in thyroid cancer. But only one case of banding observation in nodular hyperplasia have been reported. In order to compare the chromosomal changes in the thyroid cancer and the noncancerous thyroid disease, we performed cytogenetic analysis in two papillary carcinoma and two nodular hyperplasia after cell culture. The chromosomal pattern of the nodular hyperplasia found was very heterogenous but no clonal abnormaly in both cases was observed. Case I : A modal chromosomal number was in 42-46 range. Chromosome 8, 19, 21. 22 were commonly lost. 9 structural anomalities among 51 analysed cells were observed but they were not clonal. Case II: A modal chromosomal number was 43. Chromosome 17 and 19 were commonly lossed. Common cytogenetic characters of this two nodular hyperplasia are hypodiploidity and very heterogenous chromosomal pattern. The result about the papillary carcinoma are as follow. In one case some numerical and structural chromosomal changes were observed. But they were not clonal abnormality. In another case the chromosomal pattern found was very heterogenous with a clonal abnormality of del(11)(q23). The modal number was 46. The del(11)(q23) a chromosomal change in papillary carcinoma of the thyroid have previously been reported(Eva Olah et al. 1989). We suggest that 11q deletion may be important role to pathogenesis of papillary carcinoma of the thyroid. According to this results, we could not find out specific differences about chromosomal changes and any relationship between the papillary carcinoma and the nodular hyperplasia.

Tarsal tunnel syndrome caused by ganglion as space occupying lesion is unusual and known that excellent result can be expected from surgical treatment carried out soon after onset of the condition. The object of the current study is to report our experience of tarsal tunnel syndrome caused by ganglion of flexor digitorum longus tendon sheath treated with operative management in a 39 year-old man with a review of the literature.

Tarsal tunnel syndrome caused by space occupying lesion is unusual but it rarely occur by ganglion which is presented below the flexor retinaculum due to compression neuropathy of posterior tibial nerve and its branches. The object of the current study is to report our experience of surgical treatment about tarsal tunnel syndrome caused by the ganglion of flexor digitorum longus tendon sheath and multifocal myxoid degeneration of medial plantar nerve with a review of the literatures.

결핵성 임파선염은 아직도 한국에서 많이보는 질환이며 젊은여자 성인 특히 아시아인이나 흑인에서 가장 흔하다. 이 질환은 두경부에 흔히 무통성으로 서서히 림프절이 커지는 양상을 보이나 인체내 결절이 있는 어디나 오며 종격동 결절에도 온다. scrofula(선통(腺病))는 다양한 종양, 비종양성 종괴, 감염질환 특히 경부임파선염 풍과 구별되야만 한다. 비록 병력, 역학, 임상양상 흉부 엑스선 그리고 결핵반응검사로써 만족할만한 진단을 내리지만 절제생검으로 조직 및 배양이 필요하기도 하다. 궤양이나 만성 누공 형성을 막기위해 부분생검이나 절개 및 배농은 반드시 피해야 한다. 치료는 항결핵화학요법이며 가끔 외과적 적출술이 약물요법과 더불어 요구되기도 한다.

Ganglion cysts causing suprascapular nerve compression are uncommon cause of suprascapular nerve entrapment. The advent of magnetic resonance imaging and its application in patients with shoulder pain has improved the ability to diagnose cystic lesions causing extrinsic compression of the suprascapular nerve. We present two cases of suprascapular nerve compression by ganglion cyst which was decompressed by surgical excision. Suprascapular nerve compression was also revealed by magnetic resonance imaging(MRI), electromyogram(EMG) and clinical present of muscle atrophy and motor weakness. In each case, the symptom was resolved after sugical excision of the cystic lesion. We experienced two cases of suprascapular nerve entrapment by ganglion cyst and report the clinical, radiological and pathological findings in detail.

Intraosseus ganglion cysts are uncommon, benign, juxta-articular and usually found within long bones. A 35-year-old male presented with acute right ankle pain. He denied any traumatic event. Tenderness was localized on the subtalar joint. Radiologic studies demonstrated a cystic lesion in the juxta-articular portion of the posterior facet of the calcaneus. The patient underwent excision and curettage. Postoperative recovery was uneventful. A histological examination confirmed a typical intraosseus ganglion cyst. A case of an intraosseus ganglion cyst of the calcaneus causing acute subtalar joint pain is described.

Ganglion is the most common soft tissue tumor of the hand, and most of them usually arise from the scapholunate ligament, scarphotrapezial ligament, radiocarpal joint or flexor tendon sheath. However, intratendinous ganglion is very rare with unknown etiology and pathogenesis that originates within tendon. We have experienced three clinical cases of intratendinous ganglion in extensor tendons of hand. The average of patients at operation was 36 years. All patients were treated by excision of the ganglion in conjunction with tenosynovectomy followed by repair of the tendon. The length of mean follow up time was 6.7 months and all of them showed no evidence of recurrence.
