ABSTRACT

Undifferentiated gastric carcinoma is a rare histopathological type of cancer that does not show any differentiation toward adenocarcinoma or squamous cell carcinoma. It is thought to be highly malignant, and is associated with a poor prognosis. However, its clinical behavior has not yet been fully analyzed because of its rarity. We herein review the clinical characteristics and prognoses of patients with undifferentiated gastric carcinoma treated at our institutions. Among 2,651 gastric cancer patients, four (0.2 %) were histopathologically diagnosed to have undifferentiated carcinoma. These four patients included three males and one female. The median age of the patients was 60-year old (range 47-75). Three cases had distant metastases at diagnosis. One of these three cases was treated with chemotherapy alone, and the other two were treated with palliative gastrectomy and chemotherapy. The patient with no distant metastasis underwent curative gastrectomy and adjuvant chemotherapy. All patients died of cancer at a median of 5.4 (range 3.5-7.1) months after their diagnoses.

ABSTRACT

Kaposiform hemangioendothelioma (KHE) is a rare tumor that occurs nearly exclusively during infancy and childhood. It has features common to both capillary hemangioma and Kaposi sarcoma and for that reason many terms have been used for these tumors including "Kaposi-like infantile hemangioendothelioma" and "hemangioma with Kaposi sarcoma-like features." KHE typically presents as an ill-defined, red to purple, indurated plaque and is often complicated by the Kasabach-Merritt phenomenon (KMP), a condition of severe thrombocytopenia and consumptive coagulopathy. Knowledge of the radiological findings of this uncommon tumor might be helpful for diagnosis. We present the MRI features of a case of KHE with neither typical skin lesions nor the Kasabach-Merritt phenomenon.

ABSTRACT

INTRODUCTION: Infantile hepatic hemangioma with consumptive hypothyroidism is a rare condition. CASE REPORT: A 4-month-old girl presented with diffuse hepatic hemangiomas during treatment of congenital hypothyroidism. Serum reverse triiodothyronine was elevated, and her hypothyroidism improved concomitant with involution of the hemangioma following prednisolone and interferon-alpha administration. At 20 months of age, 7 months after discontinuing prednisolone and interferon-alpha, a focal hemangioma regrew from one of the previous lesions and was surgically resected. The expression and activity of type 3 iodothyronine deiodinase (D3) were elevated in the resected tumor tissue compared with placenta. DISCUSSION: Here, we describe a patient with consumptive hypothyroidism and diffuse infantile hepatic hemangiomas, one of which regrew after involution following pharmacotherapy. The etiology of elevated D3 activity is also discussed. CONCLUSION: It is important to identify infantile hepatic hemangioma in patients with hypothyroidism refractory to hormone replacement therapy, who have low free triiodothyronine despite high thyrotropin and normal free thyroxine levels, and long-term follow-up will be needed for these patients.
