Angiofibroma*

BACKGROUND: Abnormal over-expression or gene amplification of epidermal growth factor receptor (EGFR) is important in the prognosis of non-small cell lung cancer (NSCLC). We investigated the frequency of EGFR protein expression and gene amplification, and the correlation between EGFR status and survival in NSCLC. METHODS: We examined 360 cases of microarrayed NSCLC tissues for the EGFR protein expression and EGFR gene amplification using immunohistochemistry and fluorescent in situ hybridization. RESULTS: EGFR protein expression and EGFR gene amplification occurred in 110 cases (30.6%) and 24 cases (6.7%), respectively. EGFR protein expression and gene amplification were more frequent in squamous cell carcinoma than in adenocarcinoma. Differences in EGFR protein expression did not dramatically affect survival curves (p=0.740), but differences in gene amplification did (p<0.05): EGFR gene amplification was associated with a lower 5-year survival rate. CONCLUSION: EGFR protein expression and gene amplification showed moderate correlation with each other. EGFR gene amplification predicted a poor prognosis, whereas EGFR protein expression did not.

Pheochromocytoma

We report here on a rare case of sarcomatoid carcinoma that contained an epithelial component of squamous cell carcinoma. A 77-year-old woman was found to have a gallbladder mass. The gallbladder showed a diffuse infiltrative wall mass with a polypoid lesion, and the mass measured 8x7x3 cm. There were no gallstones. Histologically, the tumor was composed of two components of squamous cell carcinoma and spindle cell malignancy. The tumor extended to the perimuscular connective tissue and one regional lymph node. The postoperative course was uneventful and the patient was well without tumor recurrence at one and a half months after surgery.

Sarcoidosis and malignant neoplasm are frequently encountered pulmonary diseases, but their combined existence in the same patient is rare. As sarcoidosis usually presents as mediastinal lymphadenopathy, its concurrence in lung cancer patient radiologically mimics mediastinal metastasis and this can be possibly interpreted as unresectable disease. We report here on a case of lung adenocarcinoma associated with sarcoidosis that developed in a 64 year-old male who underwent surgical resection. Radiological examinations revealed 5.7 cm-sized mass in the right upper lobe with an enlargement of the bilateral supraclavicular, highest mediastinal, subcarinal and the upper and lower paratracheal lymph nodes. Histologic examination showed a well differentiated adenocarcinoma with non-caseating epithelioid granulomas in the lung. The enlarged peribronchial and mediastinal lymph nodes also revealed sarcoid granulomas without cancer metastasis. A good prognosis may be expected for those cases of lung cancers with non-caseating granulomas in the regional lymph nodes. The patient presently has no symptoms or signs of tumor, without further treatment since his surgery.

Ménétrier’s disease (MD), which is characterized by hypertrophic gastric folds and foveolar cell hyperplasia, is the most common gastrointestinal (GI) cause of protein-losing enteropathy (PLE). The clinical course of MD in childhood differs from that in adults and has often been reported to be associated with cytomegalovirus (CMV) infection. We present a case of a previously healthy 22-month-old boy presenting with PLE, who was initially suspected to have an eosinophilic GI disorder. However, he was eventually confirmed, by detection of CMV DNA using polymerase chain reaction (PCR) with gastric tissue, to have MD associated with an active CMV infection. We suggest that endoscopic and pathological evaluation is necessary for the differential diagnosis of MD. In addition, CMV DNA detection using PCR analysis of biopsy tissue is recommended to confirm the etiologic agent of MD regardless of the patient’s age or immune status.

Isolated tubal torsion is a rare disease that causes acute lower abdominal pain. In most of cases, the ovary and the fallopian tube are together twisted due to an ovarian tumor, but the fallopian tube alone is rarely twisted. Tubal torsion mainly occurs in fertile women, and it rarely occurs prior to menarche and during menopause. We experienced a case where isolated tubal torsion occurred in a perimenopausal female with total abdominal hysterectomy, while the findings showed a normal ovary. We report this case with a brief review of related literature.
