RESUMEN
Thoracic endometriosis (TE) is an uncommon disorder affecting women of childbearing age. We herein report clinical and thin-section computed tomography (CT) findings of two cases, in which one woman presented with catamenial haemoptysis (CH) alone and another woman presented with bilateral catamenial pneumothoraces (CP) coinciding with CH, a rare manifestation of TE. The dynamic changes demonstrated on thin-section chest CT performed during and after menses led to accurate localisation and presumptive diagnosis of TE in both patients. Following danazol treatment, the patient with CH alone had a complete cure, while the patient with CP and CH had an incomplete cure and required long-term danazol treatment. We discuss the role of imaging studies in TE, with an emphasis on the appropriate timing and scanning technique of chest CT in women presenting with CH, potential mechanisms, treatment and patient outcomes.

BACKGROUND: The diagnostic of malignancy in biopsy specimens is very important because it guides to selected treatment option and prognostic prediction. However biopsy specimens usually have small pieces leading to variations of the interpretation by anatomical pathologists. OBJECTIVE: To detect and correct the errors or the significant discrepancies in the diagnosis of biopsy specimens before sign-out and to determine the frequency of anatomic pathology significant discrepancies. DESIGN: The application of the mutually agreed work instructions (record) for the detection of errors or the significant discrepancies and their process of sign-out. The record of biopsy specimen that received a secondary check (1959 cases, 2005-2007) was analyzed. RESULTS: After a secondary check, 53 cases of non-malignancy for any reason by a second pathologist were included. However when using our definition on significant discrepancies, only 37 cases were considered. Another seven cases with the opinions with malignancy that were of different cell types that do harm to the patients were added. Therefore, 44 cases (2.25%) had truly significant discrepancies. CONCLUSION: The truly significant discrepancy frequency was 2.25% during the process of pre-sign-out secondary check of malignancy of biopsy specimens. The project has been applied as a routine daily work. It can be an innovative safety program for patient in Thailand.

BACKGROUND: Pythiosis is an emerging and life-threatening infectious disease in humans and animals that is caused by the pathogenic oomycete Pythium insidiosum. Human pythiosis is found mostly in Thailand, although disease in animals has been increasingly reported worldwide. Clinical information on human pythiosis is limited, and health care professionals are unfamiliar with the disease, leading to underdiagnosis, delayed treatment, and poor prognosis. METHODS: To retrospectively study the clinical and epidemiological features of human pythiosis, we analyzed clinical data from patients with pythiosis diagnosed during the period of January 1985 through June 2003 at 9 tertiary care hospitals throughout Thailand. RESULTS: A total of 102 cases of human pythiosis were documented nationwide. A substantial proportion (40%) of cases occurred in the last 4 years of the 18-year study interval. Clinical presentations fell into 4 groups: cutaneous/subcutaneous cases (5% of cases), vascular cases (59%), ocular cases (33%), and disseminated cases (3%). Almost all patients with cutaneous/subcutaneous, vascular, and disseminated pythiosis (85%) had underlying thalassemia-hemoglobinopathy syndrome. Most ocular cases (84%) were associated with no underlying disease. A majority of the patients were male (71%), were aged 20-60 years (86%), and reported an agricultural occupation (75%). Regarding treatment outcomes, all patients with disseminated infection died; 78% of patients with vascular disease required limb amputation, and 40% of these patients died; and 79% of patients with ocular pythiosis required enucleation/evisceration. CONCLUSIONS: Here, we report, to our knowledge, the largest case study of human pythiosis. The disease has high rates of morbidity and mortality. Early diagnosis and effective treatment are urgently needed to improve clinical outcomes. Because P. insidiosum is distributed worldwide and can infect healthy individuals, an awareness of human pythiosis should be promoted in Thailand and in other countries.

Leiomyoma is common in the myometrial layer of the uterus, and rarely found in other genital organs. Previous reports show multiple sites of leiomyoma outside the uterus eg. vagina, oral mucosa or mandible vascular leiomyoma. Leiomyoma is normally a benign smooth muscle tumor and behaves as a hormone sensitive tumor Leiomyomas develop during the reproductive age and regress after menopause. The case of a 25 year old female with a large left labial leiomyoma presented as Bartholin's cyst. Illustrates the diagnostic difficulties in such cases. The management in this case was surgical excision. The definite diagnosis was confirmed by histologic examination as a labial leiomyoma.

Angiosarcoma is a relatively uncommon primary malignant tumor of the heart derived from the endothelial cells. The authors report a case of primary cardiac angiosarcoma of the right atrium with pulmonary, hepatic, cerebellar and bony metastases in a 46-year-old man who clinically presented as pulmonary hemorrhage. The patient's occupational history had occasional exposure to polyvinyl chloride. The autopsy examination of the cardiac angiosarcoma characterized macroscopically by a right atrial tumor and histologically by anastomosing vascular channels and minute atypical pleomorphic endothelial cells. Immunohistological stainings were positive CD31, CD34 and focal positive factor VII-related antigen. Clinical and pathologic features with briefly reviewed relevant literatures are discussed This is the first reported description in the literature of a primary cardiac angiosarcoma with systemic metastases to multiple organs in Thailand.
