BACKGROUND Lipoma is a benign neoplasm originated from adipose cells circumscribed by connective tissue. This neoplasm represents about 1% to 4.4% of all oral benign tumors and it is rarely located in the palate area. OBJECTIVE This case reports the occurrence of an oral lipoma in the hard palate of a 57-year-old woman and discusses its etiology and treatment. CASE REPORT The treatment cons...

BACKGROUND Retroperitoneal lipoma is an extremely rare neoplasm. AIMS The authors report a case of giant retroperitoneal lipoma in a 32-year-old white female, with a history of pain and an abdominal mass over a 2-year period. Total abdominal ultrasonography and barium enema showed a large mass located in the retroperitoneal space behind the ascending colon. Laparotomy showed a large encapsula...

The presence of signet-ring cells in an endometrial adenocarcinoma is extremely uncommon and it is always necessary to rule out a metastatic neoplasm. We report a FIGO grade 2 endometrial carcinoma with a signet-ring cell component found in the curettage performed to a 53-year-old woman. The neoplastic proliferation was also found in the endometrium of the radical hysterectomy with bilateral sa...

Retroperitoneal malignant mesenchymoma is a rare retroperitoneal neoplasm with poor prognosis. Here we present a patient with retroperitoneal malignant mesenchymoma. A 32year-old man presented with progressive painful swelling on his left lower leg, abdominal fullness and a palpable left abdominal mass. Imaging studies of abdomen included sonography, contrastenhanced computed tomography (CECT) ...

Solid pseudopapillary neoplasm (SPN), also known as Gruber-Frantz tumor, is a rare form of neoplasm that almost exclusively occurs in the pancreas and in young females. While the potential of malignancy is low for SPN, these tumors can mimic other diseases and require a meticulous investigation and a standard treatment by total surgical resection. We present an unusual case of SPN arising in th...

INTRODUCTION Mammary-type myofibroblastoma of the soft tissue is a very rare, benign, mesenchymal neoplasm with myofibroblastic differentiation. To date, 20 cases of extra-mammary myofibroblastoma have been described in literature. To the best of our knowledge, this is the largest extra-mammary myofibroblastoma described in the literature, and the first case reported in this location. CASE PR...

BACKGROUND Hyalinizing clear cell carcinoma (HCCC) is a rare neoplasm of salivary gland origin which is low-grade in nature. In this series, we report on 9 cases of HCCC and update the literature. METHODS A comprehensive literature search was performed. Our institutional database was queried for cases of HCCC. Pathology reports and slides were reviewed. Data was extracted, including demograph...

This case was an old woman who had been suffering from peripancreatic space occupying lesions for more than 3 years. She underwent distal pancreatectomy and splenectomy. Under a microscopic examination, the tumor was composed of well-differentiated mucinous cystic neoplasm (MCN) and poorly differentiated anaplastic giant-cell carcinoma. Tumor giant-cells engulfing the neutrophils were visible i...

The purpose of this paper is to outline an application of number theory in medicine. More specifically, a linear second-order recurrence relation is utilized in a technique for the diagnosis of breast cancer. This continues a tradition in this journal of applications of second-order recurrences. Indeed, the very first issue contained an article by Basin [1] on the Fibonacci sequence in art and ...
