Basal cell adenocarcinoma is a extremely rare low grade malignancy of the salivary gland. It is composed of basaloid cells with dark cell, light cells and pale cytoplasm which shows infiltrative growth pattern into adjacent glandular parenchyme. The pathophysiology of basal cell adenocarcinoma is not well known. First hypothesis is a malignant transformation of the monomorphic adenoma and second one is a de novo origin. Metastasis to the regional lymph nodes is rare. Recently, we have experienced a case of basal cell adenocarcinoma with neck metastasis after previous superficial parotidectomy. For this reason we report this rare case discussed with references.

Kaposiform hemangioendothelioma (KHE) is a very rare, locally aggressive vascular neoplasm. It occurs mostly in children and is rarely observed in adults. It typically originates on the skin, later affecting the deep soft tissue of the extremities, head or neck, and retroperitoneum by infiltrative growth. It is locally aggressive, does not regress spontaneously, and tends to metastasize locally as well as to the regional lymph nodes. In this article, we report a case of adult-onset KHE with neurofibromatosis type 1. The patient presented to our department with a 2-month history of a painful ulceration in her left popliteal area. Since KHE had not previously been reported in patients with neurofibromatosis, the diagnosis was difficult due to the similarity of the skin manifestation to neurofibromatosis-associated lesions. We share our experience of diagnosing and treating this rare case of adult-onset KHE.

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.

흉부방선균증은 임상양상 및 방사선학적 소견이 폐의 기타 염증성 질환이나 악성암과 유사한 경우가 많아 감별진단에서 놓치기 쉬우나, 대부분 항생제 치료에 좋은 반응을 보이므로 조기진단을 위한 적극적 접근으로 심각한 합병증의 발생 및 불필요한 수술을 막아야 한다. 저자들은 폐암을 의심하여 시행한 검사도중 폐를 침범하는 방선균증을 경험하였기에 문헌고찰과 함께 보고하는 바이다.

Prostate cancer is the second most common cause of cancer death in men in the United States. The most common sites of metastasis include the bone, lymph nodes, lung, liver, pleura, and adrenal glands, whereas metastatic prostate cancer involving the gastrointestinal tract has been rarely reported. A 64-year-old African-American man with a history of prostate cancer presented with anemia. He reported the passing of dark colored stools but denied hematemesis or hematochezia. Colonoscopy revealed circumferential nodularity, and histology demonstrated metastatic carcinoma of the prostate. Esophagogastroduodenoscopy showed hypertrophic folds in the gastric fundus, and microscopic examination revealed tumor cells positive for prostate-specific antigen. Bone scanning and computed tomography of the abdomen and pelvis did not show metastasis. It is crucial to distinguish primary gastrointestinal cancer from metastatic lesions, especially in patients with a history of cancer at another site, for appropriate management.

Malignant melanoma develops from melanocytes and frequently metastases to other organs. Common metastatic sites are other skin, lymph nodes, lung, liver, brain and bone in decreasing order of frequency. Malignant pleural effusion is less frequent manifestation of thoracic metastasis. We experienced a 57-year-old man with pleural effusion who received radical resection with local flap on left foot due to acral lentiginous melanoma 3 years ago. He had progressive chest pain and left massive pleural effusion. The pleural cytology and biopsy showed malignant melanoma. After closed thoracostomy and talc pleurodesis, he refused further immunotherapy and chemotherapy and discharged.

Introduction: Distant metastases of mucoepidermoid carcinoma (MEC) are reported with the most common sites being the soft tissue of skin, lung, liver, and bone. We report here a very rare case of MEC with multiple metastases to the kidney, adrenal gland, skull and gluteus maximus muscle. Case report: A 63-year-old male patient presented with left-sided headache. Radiologic evaluations including CT and MRI showed ill-defined soft tissue lesion involving the left infratemporal fossa and left sphenoid sinus, and multiple enlarged lymph nodes in neck and mediastinum. PET-CT demonstrated multiple hypermetabolic lesions in and around the left kidney, left adrenal gland, right ischium, right gluteus maximus and skull base. These lesions were confirmed as MEC with multiple metastases through biopsy. Discussion: Only one case of metastasis to the skull has been previously reported, and moreover, there has not been a case of metastatic MEC to the kidney, adrenal gland and gluteus maximus muscle so far in the medical literature. It is important to acknowledge the possibility of every unusual MEC metastases, since the presence of metastasis has statistically significant influence on the survival of MEC.

A 1.5-year-old male Golden Retriever was presented with worsening lameness of two month duration. Abnomral findings of blood works and serum chemistry included anemia, thrombocytopenia, hypercalcemia and hyperglobulinemia. Radiography revealed osteolysis of polyostotic regions including right femur and tibia, bilateral ilium, and spinous processes from the 13th thoracic vertebra to 5th lumbar vertebra. Enlarged multiple lymph nodes and mixed echo pattern of muscular region ventral to vertebra were observed with ultrasonography. Because concentrations of both parathyroid hormone and parathyroid hormone related peptide were all within reference ranges, humoral hypercalcemia by tumor was ruled out and extensive osteolysis was considered as the cause of hypercalcemia. Based on radiographic and ultrasonographic study, lymphoma, multiple myeloma and osteomyelitis were included in differential diagnosis. Fungal serologic test was negative. Monoclonal gammopathy was not found on serum protein electrophoresis. Cytological and histopathological examinations of the lytic lesions revealed neoplastic lymphoid proliferation, and B cell type clonal expansion was detected by polymerase chain reaction for the antigen receptor gene rearrangement. The case was diagnosed as B cell lymphoma involving polyostotic regions.

Kikuchi's disease is a self-limiting benign disease characterized by cervical lymphadenopathy, but it can be mistaken for malignant disease, and when involved lymph nodes are unusually located, diagnosis can be more difficult. The authors report the case of a 19-year-old man with Kikuchi's disease, who had isolated intra-abdominal lymphadenopathy and increased 18-fluoro-deoxyglucose (FDG) uptake in positron emission tomography-computed tomography (PET-CT). Although its incidence is extremely rare, intra-abdominal Kikuchi's disease with increased FDG uptake in PET-CT image should be considered in the differential diagnosis when constitutional symptoms mimic those of malignant lymphoma.
