Pulmonary blastoma is a family of tumors in which the glands or mesenchyme composing the neoplasm are primitive or embryonic in appearance. There are three subtypes, which include well differentiated fetal adenocarcinoma (pulmonary endodermal tumor), biphasic pulmonary blastoma, and cystic and pleuropulmonary blastomas in children. Among them, biphasic pulmonary blastoma is a primary malignancy of the lung originating from multipotential pulmonary blastema including both the malignant fetal epithelial and mesenchymal components. These make up 0.25 to 0.5 percent of all primary malignant lung tumors. This tumor is usually symptomatic and appears as a large, solitary peripheral mass, with a tendency to favor the upper lobe. Here we report a case where a small sized asymptomatic peripheral lung mass was diagnosed as a biphasic pulmonary blastoma, prior to the operation, A subsequent percutaneous needle biopsy was performed, which revealed features of a large cell neuroendocrine tumor. In addition, a review of the relevant literature is provided.

Desmoid tumor (fibromatosis) is a histologically benign fibrous neoplasm showing locally infiltrating growth. This type of tumor commonly occurs in the abdomen, but intrathoracic desmoid tumor is uncommon. To date, 12 cases of intrathoracic desmoid tumor protruding into the pleural cavity, radiologically mimicking pleural masses, have been reported. Here, we report on a case of intrathoracic desmoid tumor protruding into the pleural cavity, and partially covered by parietal pleura. The main preoperative differential diagnoses included pleural solitary fibrous tumor, inflammatory pseudotumor or malignant mesothelioma. A near-total mass excision was performed. Pathologically, the tumor was composed of a paucicellular arrangement of spindle-shaped cells with fibromyxoid stroma. The resection margin was partially involved with spindle cells present. On histochemical staining, the spindle cells were strongly positive for vimentin and negative for CD34, consistent with a desmoid tumor. The patient was stable without further adjuvant treatment during 6-years of follow-up.

Morus alba, known as White Mulberry, is one of the most common species of mulberry found in South Korea, along with M. australis, known as Korean Mulberry. During a routine survey to investigate fungal diseases on deciduous broad-leaved trees in 2020, leaf spots were consistently observed on the White Mulberry in Sejong-si (36°30'12.8"N 127°17'34.5"E) and Wonju-si (37°15'29.6"N 128°11'37.9"E), South Korea, with a disease incidence of approximately 70 to 80%. Symptoms included circular, tan or necrotic lesions surrounded by a dark margin on leaves, which, in some cases, the lesions coalesced to form relatively large necrotic regions. The pathogen was successfully isolated from M. alba, and was identified as Cladosporium pseudocladosporioides based on the phylogenetic analysis and morphology. To the best of our knowledge, this is the first report of leaf spot disease on M. alba caused by C. pseudocladosporioides in South Korea.

Pigmented villonodular synovitis is a rare proliferating process of the synovium, tendon sheaths and bursae usually affecting the bone and joints. The disease can be localized or diffuse. Patients with this condition typically present with symptoms of mild discomfort and associated swelling of the involved joint. However, the spectrum of presentations is broad. Diagnosis of Pigmented villonodular synovitis can be clinically difficult, and plain radiographs are usually nonspecific. Magnetic resonance imaging is a highly diagnostic modality in characterizing pigmented villonodular synovitis when it contains hemosiderin deposits exhibiting low signal intensity on all pulse sequences. Magnetic resonance imaging is recommended for accurate preoperative staging of the disease and for follow up after treatment. I report a case of pigmented nodular synovitis in the knee joint, with review of literatures.

A potyvirus causing chlorotic mottle and yellow spots on leaves of Dianthus barbatus was isolated and identified as an isolate of Carnation vein mottle virus (CVMV). Purified preparations of Chenopodium quinoa infected with CVMV-K showed filamentous particles between 695 and 785 om long. Many cytoplasmic inclusions were observed, and these consisted of pinwheels, dense bands, loops, and circles. The coat protein of CVMV-K was about 32 KDa in western blot analysis using a CVMV antibody. The nucleotide sequence of coat protein gene showed 97.6％ homology with a Japanese isolate. The genome size of CVMV-K was about 9.0 kb by dsRNA analysis. These results indicate that the virus is an isolate of CVMV. This is the first report on CVMV in Korea.

Most plants of commercial poinsettia cultivars grown from cuttings develop mosaic and chlorotic dot symptoms on leaves. Reverse transcription-polymerase chain reaction (RT-PCR) test showed that they were infected with Poinsettia mosaic virus (PnMV). In a survey of commercially grown poinsettias conducted in Korea, PnMV was detected in ten of ten poinsettia cultivars sampled and in 100％ of 178 samples tested. The virus has isometric particles and about 29 nm in diameter. Crystalline virus particles were observed in cytoplasm of cells of diseased plants by transmission electron microscopy. Nucleotide sequence of coat protein gene of PnMV- Kl showed 97.3％ homology with that of a German isolate. This is the first report on PnMV in Korea.

Leiomyoma is a type of benign smooth muscle neoplasm that is a common neoplasm of the uterus and gastrointestinal tract but rarely affects the head and neck region and is especially unlikely to affect the oral cavity. The diagnosis of leiomyoma is mainly determined by histopathological studies due to variation in its clinical appearance and symptoms. In the present paper we report two rare cases of gingival angioleiomyoma in the posterior maxilla and mandible. After total excision, hematoxylin-eosin and smooth muscle actin staining confirmed the diagnosis of angioleimyoma.

A nasal-type extranodal natural killer/T-cell lymphoma is considered an aggressive form of non-Hodgkin's lymphoma, with approximately half of all patients relapsing during the follow-up period, and most relapses occurring within the first 2 years of remission. Here we report an unusual case of a 42-year-old man who experienced recurrence in single pleura after 8 years of remission.

Epithelioid sarcoma is a malignant soft tissue neoplasm with an uncertain histogenesis. We report the imprint cytologic features of epithelioid sarcoma in the left shoulder of a 29-year-old male patient. Imprint cytologic findings showed dissociated and loose aggregates of anaplastic epithelioid cells on the necrotic, bloody, and inflammatory background. Tumor cells were round to polygonal shaped. Tumor cells had vesicular nuclei with abundant cytoplasm. The nuclei were irregular in shape and often eccentrically located. Some tumor cells were oval to spindle shaped. Binucleated and multinucleated cells were found. Intracytoplasmic vacuoles were present. On immunohistochemical stain, the tumor cells were positive for epithelial membrane antigen, vimentin, and CD34.

Vaginal dryness is not a rare complaint of postmenopausal women. But the concerns and treatments about this were negative in patients and doctors. So we treated with Gagam-chungsimyeonjaeum(加減淸心蓮子飮) on three cases complaining vaginal dryness. As a result vaginal dryness was improved in all cases. Through this case report, we expect that more interests and participations in vaginal dryness will be got more qualities in life of postmenopausal women.
