Pancreatic metastasis from malignant phyllodes tumor (PT) of the breast is rare, and only a few cases have been reported in the literature. Here, we report a case of pancreatic metastasis from malignant PT of the breast in a 48-year-old woman. She had had three episodes of recurrence of malignant PT in her right breast. She presented with epigastric pain for 2 months. Computed tomography and magnetic resonance imaging revealed a 6 cm-sized, well-defined, heterogeneous mass with peripheral enhancement in the body of the pancreas. Endoscopic ultrasonography-guided fine-needle aspiration was performed, and the pathologic report suggested spindle cell mesenchymal neoplasm. Subsequently, surgical excision was performed, and the mass was confirmed as a metastatic malignant PT. The imaging findings are discussed and the literature is briefly reviewed in this report.

Abstract PDF

Mammary Paget’s disease (MPD) is usually accompanied by underlying breast malignancy; however, a few cases have been reported as only skin lesions without any evidence of malignancy of the breast on imaging tests and microscopic examination of surgical specimen. Here, we describe a 47-year-old woman who visited our hospital who had an eczematous lesion on right nipple and areola for over 10 years. The lesion was diagnosed as Paget’s disease by punch biopsy; however, imaging studies demonstrated no breast malignancy or lymph node metastasis. The patient underwent surgery of on the nipple and areola including underlying breast tissue. No underlying malignancy was found upon microscopic examination, except for Paget’s disease. Immunohistochemical stains revealed that the tumor cells were positive for cytokeratin 7, and negativity for p63, cytokeratin 5/6, estrogen receptor, progesterone receptor, and human epidermal growth factor receptor 2. We report a case of MPD without underlying malignancy. To the best of our knowledge, this is the third case reported in Korea.

Abstract PDF: Gastric cancer is the most common cancer in Korean males and can easily spread to distant organs such as the liver, lungs, brain, or bones. However, skin metastasis, particularly of the eye, is rare. Metastatic eyelid cancer is extremely rare; metastases from internal organs have not been reported so far. We recently experienced a patient with metastatic eyelid cancer from adenocarcinoma of the stomach. A 62-year-old female was admitted with a right upper eyelid mass and foreign body sensation. She had a history of stomach cancer of 3 years. She was treated by chemotherapy and radiotherapy for pathologic fracture. After receiving supportive care for 2 years, the mass appeared on her right pupil. Punch-biopsy of the mass was performed and histological examination revealed adenocarcinoma, the same as the initial histological result. We report this case with a review of related literature.

Abstract PDF: Multiple symmetric lipomatosis (MSL) is a rare disease characterized by symmetrical massive fatty deposits on the face, neck, shoulders, and upper trunk. We report a 74-year-old man who complained of painless subcutaneous nodules on his posterior neck that developed 3 weeks earlier. In a week, variably-sized similar lesions developed on both his shoulders and upper extremities. At the time of his hospital visit, several firm nodules as big as a walnut to a child's fist and with the normal-skin-hue were observed on his posterior neck, both shoulders, upper extremities, and trunk. The histological examination of his upper left arm revealed more mature adipocytes without encapsulation in the subcutaneous tissue. MSL was generally known to occur slowly over months or years. However, this is an unusual case that showed a fast-growing nature.

Abstract PDF

Allogeneic hematopoietic stem cell transplantation (HSCT) is considered the optimal curative treatment for acute myeloid leukemia (AML), but some patients develop bone marrow relapse due to remnant leukemia, and few patients develop extramedullary relapse without bone marrow relapse. Isolated extramedullary relapse (IMER) is defined as extramedullary relapse without bone marrow relapse. IMER has been reported in various sites, including the skin, soft tissue, and central nervous system(CNS). Isolated CNS relapse is relatively rare and is associated with poor prognosis due to the absence of an optimal treatment for it. Reported herein is a case involving an adult AML woman who suffered from isolated extramedullary relapse in the CNS after allogeneic HSCT. She was treated with intrathecal chemotherapy and whole-brain and spine radiotherapy, followed by systemic chemotherapy. She is currently well, with no evidence of leukemia recurrence for over six years.

Abstract PDF: The incidence of hepatocellular carcinoma presenting as obstructive jaundice is 0.7~9%. The mechanisms of obstructive jaundice include bile duct invasion by tumor, tumor thrombi, blood clots, direct bile duct compression by tumor, and intraductal tumor growth. We report a rare case of hepatocellular carcinoma with intraductal growth. A 46-year-old woman was admitted due to colicky right upper abdominal pain and jaundice for 4 days. Computed tomography showed dilatation of the left intrahepatic duct, and endoscopic retrograde cholangiography showed a filling defect in the left main intrahepatic duct. We performed a left lobectomy with a Roux-en-Y hepaticojejunostomy. The tumor was diagnosed as a hepatocellular carcinoma with intraductal growth.

Abstract PDF

Breast conserving surgery has become the preferred method of treatment for breast cancer. Therefore clear surgical margin is critical to minimize the risk of local recurrence. Although paraffin section of inked surgical margin is the gold standard for margin assessment, this process is time consuming, and results are not available until after the operation. Several methods of intraoperative margin assessment are available including gross evaluation of the tumor specimen, specimen slice radiography, pathologic evaluation with touch preparation cytology or frozen section analysis. Here I review three methods of pathologic evaluation -macroscopic evaluation, touch preparation cytology, and frozen section- and deal with problems and pitfalls that can happen in routine diagnostic fields.

Abstract PDF: Adenoid cystic carcinoma (ACC) is a rare malignant neoplasm of the breast accounting for approximately 0.1% of all breast carcinomas with a total 200 cases reported in the literature. In contrast to the aggressive nature of ACC in other organs, ACC of the breast is known to have an excellent prognosis. Recently we experienced the first case of ACC of the breast at Yeungnam University hospital. The case was diagnosed by preoperative fine needle aspiration cytology. We report a case of ACC of the breast managed with breast conserving surgery and review the literature.

Abstract PDF: Chordoma is a slow-growing malignant neoplasm arising from the remnants of the primitive notochord. It accounts for 1 to 4% of all malignant bone tumors. It occurs exclusively along the spinal axis. Authors experienced four cases of chordoma occurred in the sacrococcygeal region. There were two male and two female patients, with a mean age of 63.5 years(range. 57~75 years). Tissue was obtained by wide excision in two patients, by incisional biopsy in one patient and by needle biopsy in the other. Adjuvant radiation theraphy was performed on all the patients after their biopsy. The mean diameter of the tumors was 7.6cm(range, 5.5 to 13.0cm). Grossly, tumor was multilobulated, soft and myxoid gelatinous mass. Microscopically, the tumor showed lobulated feature divided by fibrous septa within it. There were physaliphorous cells with vacuolated bubbly cytoplasm. And small uniform, round, and non-vacuolated tumor cells were also present. On immunohistochemical stain, all the cases were immunoreactive for cytokeratin, epithelial membrane antigen(EMA) and vimentin, respectively. One of the 4 cases was positive for S-100 protein. All the cases were negative for CEA.
