Calcification and ossification of colon cancer is frequently encountered, especially in the mucinous carcinoma. However, cartilage formation or enchondral ossification has rarely been described in human colon cancer. This report describes a case of a 59-year-old man with retroperitoneal metastasis of mucinous adenocarcinoma of colon, which showed a widespread heterotopic ossification through membranous or enchondral ossification. The ossification appeared in apposition to tumor cell nests and in the organized mucin pool. In our knowledge, this is the first case showing enchondral ossification in gastrointestinal carcinoma in Korea.

Melanosis duodeni is an uncommon pathologic condition characterized by diffuse small black spots on the first and second portions of the duodenum. It occurs predominantly in elderly patients and is linked to chronic renal failure, use of antihypertensive drug and oral iron supplementation, and/or presence of gastric hemorrhage. We report a case of melanosis duodeni in a 60-year-old woman diagnosed with hypertension 20 years ago and chronic renal failure 6 years ago. She has taken antihypertensive drugs for many years. On endoscopy, speckled black pigmentation of duodenal mucosa was detected. Microscopically, this duodenal lesions showed numerous coarse pigments in macrophages confined within the lamina propria. By ultrastructural study, macrophages contained electron-dense granules admixed with lipofuscin-like material in residual bodies.

A case of clear cell adenocarcinoma arising in the female urinary bladder, which is accompanied by endometriosis of the urinary bladder and the uterus, is reported. The carcinoma protruded into the vesical lumen as a fungating mass, and had a tubulocyotic pattern. The tumor cell had intracytoplasmic glycogen and electron microscopically short microvilli on their surface, resembling clear cell acenocarcinoma of the female genital tract including ovary. This is the fourth case report of clear cell adenocarcinoma complicating vesical endometriosis, and may support the view that clear cell carcinome arises from endometriosis which, in turn, from the Mullerian remnant.

PURPOSE: Piccolo et al. advocated the usefulness of Tc-99m-MDP breast scan in differential diagnosis of breast mass with high accuracy. But there are little or no follow-up studies about it as we know. We studied Tc-99m-MDP uptake pattern and lesions/background ratio in patients complaining palpable breast lesions to evaluate the clinical usefulness of Tc-99m-MDP scan. MATERIALS AND METHODS: Total 34 patients were studied with physical examination, mammogram and Tc-99m-MDP scan prospectively. Anteroposterior and both lateral view of breast were obtained 5 minutes after iv injection of 740 MBq Tc-99m-MDP. Breast uptake pattern of Tc-99m-MDP was analyzed by a grade system: 0=no uptake, grade 1=bilateral diffuse uptake, grade 2=asymmetric faint uptake, grade 3=focal hot uptake. 20 cases were pathologically confirmed by excision biopsy or aspiration biopsy. 14 cases were normal in physical examination and mammo-grain. RESULTS: Pathologic results showed 7 carcinomas, 6 benign solid tumors, and 7 fibrocystic changes. Grade 3 pattern of Tc-99m-MDP uptake was noted in 4/7 carcinomas, 3/6 benign solid tumors, and 1/7 fibrocystic changes. Grade 2 pattern was 2/7, 0/7, 3/7 respectively. The average L/B ratio was 1.66 in carcinomas, 1.68 in benign solid masses, 1.20 in fibrocystic diseases, 1.05 in normal patients. L/B ratio was higher in carcinoma and benign mass groups than in fibrocystic change and normal control groups(p=0.005). But there was no statistical difference between L/B ratio of malignant mass group and benign mass group. CONCLUSION: Tc-99m-MDP scan is not suitable to routine clinical use for breast mass diagnosis. It might be used in limited conditions when whole body bone scan is planned.
