- Testicular synovial sarcoma: a case report. [Journal Article]
- Cancer Biol Med 2012 Dec; 9(4):274-6.
This paper reports a case of testicular synovial sarcoma with molecular genetic analysis. A 24-year-old male presented with painless scrotal mass. Ultrasonography showed a heterogeneous mass of 66 mm × 34 mm in size involving the inguinal region. Histological examination of a surgical biopsy showed a grade III monophasic growth pattern of spindle cell proliferation. Immunohistochemical analyses indicated positive staining for pancytokeratine and epithelial membrane antigen. Cytogenetic analysis showed the presence of CYT-SSX1 mutation, and CT scan showed non-specific pleural micro-nodules with a size of 7.5 mm. The patient had an extended left orchidectomy but was lost to follow-up for 1 year. A local recurrent scrotal mass of 32 mm × 25 mm, multiple inguinal lymph nodes, and increased pleural nodules, which were confirmed by histological examination, were treated with three cycles of adriamycine and ifosfamide chemotherapy, surgical resection, and radiotherapy with complete response. After 3 months, the patient developed local recurrence and pulmonary metastases that did not respond to second-line chemotherapy based on gemcitabine and paclitaxel. The patient had dyspnea at the time of this writing and chest pain, and is under third-line chemotherapy based on Deticene after 30 months of following up. This patient died on November 16, 2012 after a resperatory failure and malignant pelural effusion. Synovial sarcoma should be considered in the differential diagnosis of soft tissue tumor and it should be aggressively treated to improve prognosis. Although our patient has shown numerous factors of bad prognosis, he has had a relatively long survival time.
- Radiation recall reaction: two case studies illustrating an uncommon phenomenon secondary to anti-cancer agents. [Journal Article]
- Cancer Biol Med 2012 Sep; 9(3):202-4.
Radiation recall phenomenon is a tissue reaction that develops throughout a previously irradiated area, precipitated by the administration of certain drugs. Radiation recall is uncommon and easily neglected by physicians; hence, this phenomenon is underreported in literature. This manuscript reports two cases of radiation recall. First, a 44-year-old man with nasopharyngeal carcinoma was treated with radiotherapy in 2010 and subsequently developed multi-site bone metastases. A few days after the docetaxel-based chemotherapy, erythema and papules manifested dermatitis, as well as swallowing pain due to pharyngeal mucositis, developed on the head and neck that strictly corresponded to the previously irradiated areas. Second, a 19-year-old man with recurrent nasal NK/T cell lymphoma initially underwent radiotherapy followed by chemotherapy after five weeks. Erythema and edema appeared only at the irradiated skin. Both cases were considered chemotherapeutic agents that incurred radiation recall reactions. Clinicians should be knowledgeable of and pay attention to such rare phenomenon.
- Combined Therapy against Recurrent Hemangiopericytoma: A Case Report. [Journal Article]
- Cancer Biol Med 2012 Jun; 9(2):141-3.
Department of Oncology, The Third Affiliated Hospital of Soochow University, Changzhou 213003, China A patient with a seven-year history of recurrent metastatic hemangiopericytoma (HPC) was admitted. During his treatment, he received surgical resection, radiotherapy, radiofrequency hyperthermia and chemotherapy using combined doxorubicin, dacarbazin, vincristine, ginsenoside Rg3, and recombinant human endostatin. This synergistic method provides an encouraging model for treating HPC.
- A novel t(3;12)(q21;p13) translocation in a patient with accelerated chronic myeloid leukemia after imatinib and nilotinib therapy. [Journal Article]
- Cancer Biol Med 2013 Mar; 10(1):47-51.
The acquisition of secondary chromosomal aberrations in chronic myeloid leukemia (CML) patients with Philadelphia chromosome-positive (Ph+) karyotype signifies clonal evolution associated with the progression of the disease to its accelerated or blastic phase. Therefore, these aberrations have clinical and biological significance. T(3;12)(q26;p13), which is a recurrent chromosomal aberration observed in myeloid malignancies, is typically associated with dysplasia of megakaryocytes, multilineage involvement, short duration of any blastic phase, and extremely poor prognosis. We have identified a recurrent reciprocal translocation between chromosomes 3 and 12 with different breakpoint at bands 3q21 in the malignant cells from a 28-year-old man. The patient was initially diagnosed as having Ph+ CML in the chronic phase. The t(3;12)(q21;p13) translocation occurred 4 years after the patient was first diagnosed with CML while undergoing tyrosine kinase inhibitor therapy. We confirmed the t(3;12)(q21;p13) translocation via fluorescence in situ hybridization assay by using whole-chromosome paint probes for chromosomes 3 and 12. Our findings demonstrate that, similar to other recurrent translocations involving 3q26 such as t(3;3) and t(3;21), the t(3;12)(q21;p13) translocation is implicated not only in myelodysplastic syndrome and acute myeloid leukemia but also in the progression of CML. These findings extend the disease spectrum of this cytogenetic aberration.
- Spontaneous pineal apoplexy in a pineal parenchymal tumor of intermediate differentiation. [Journal Article]
- Cancer Biol Med 2013 Mar; 10(1):43-6.
Pineal apoplexy is a rare clinical presentation of pineal parenchymal tumors. We report the curative treatment of a case of pineal parenchymal tumor of intermediate differentiation with spontaneous apoplectic hemorrhage. This case is shown through computed tomography and magnetic resonance imaging of the brain, and is confirmed via histopathological studies. Recurrent upward gaze paresis was observed after the stereotactic biopsy. The paresis required an expeditious tumor resection. The mechanism of the pineal apoplectic hemorrhage remains unclear although it has been observed in different pineal region lesions. Clinical and radiological evidence of the cure 5 years post-surgery is available.
- Stump appendicitis: an uncompleted surgery, a rare but important entity with potential problems. [Journal Article]
- Case Rep Surg 2013.:972596.
Appendicectomy for appendicitis is one of the commonest surgical procedures performed worldwide. The residual appendiceal stump left after an initial appendectomy risks the development of stump appendicitis. Stump appendicitis is a real recognized entity but not often considered when evaluating patients with right lower quadrant abdominal pain, especially those with past history of appendectomy. It remains a clinical challenge with the result that its diagnosis and effective treatment are often delayed with possible attendant morbidity or mortality. Stump appendicitis results from obstruction of the lumen of the remaining appendix stump, usually by a faecolith. This increases intraluminal pressure, impairing venous drainage and allowing subsequent bacterial infection. We present the case of a twenty-five (25)-year-old female who underwent laparoscopic appendicectomy and presented four and half (4(1/2)) months later with fever, right lower quadrant abdominal pain, and tenderness associated with repeated vomiting. Exploratory laparotomy was carried out after clinical and imaging studies which revealed big inflammatory mass with abscess at the right iliac fossa and recurrent appendicitis of the appendiceal stump. Surgical treatment is easy but recognition of this important entity but potentially dangerous condition should always be borne in mind in order to avoid delay in its diagnosis and treatment.
- Asymptomatic cholecystocolonic fistula: a diagnostic and therapeutic dilemma. [Journal Article]
- Case Rep Surg 2013.:754354.
Cholecystocolonic fistulas (CCF) are rare complications of gallstones with a variable clinical presentation. Despite modern diagnostic tools, cholecystocolonic fistulas are often asymptomatic and it is difficult to diagnose them preoperatively. Biliary-enteric fistulae have been found in 0.9% of patients undergoing biliary tract surgery. The most common site of communication of the fistula is the cholecystoduodenal (70%), followed by the cholecystocolic (10-20%), and the least common is the cholecystogastric fistula. Herein, we report a case of female patient with multiple episodes of acute recurrent cholangitis due to common bile duct and gallbladder stones in which preoperative imaging studies were negative for cholecystocolonic fistula that was incidentally discovered and treated during surgery and was appropriately treated. A review of the literature is reported too.
- Microscopic colitis: epidemiology, pathophysiology, diagnosis and current management-an update 2013. [Journal Article]
- ISRN Gastroenterol 2013.:352718.
Microscopic colitis is a common cause of chronic diarrhea. Over the last years the incidence and the prevalence of microscopic colitis are rising and this rise is largely attributed to a rising awareness, and concomitantly an increasing number of diagnoses are made. Patients with microscopic colitis report watery, nonbloody diarrhea of chronic, intermittent, or chronic recurrent course. Following an unremarkable physical examination the diagnosis of microscopic colitis is made by colonoscopy, which shows essentially a normal colonic mucosa. Biopsies taken during the colonoscopy procedure will then finally establish the correct diagnosis. Histological workup can then confirm a diagnosis of microscopic colitis and can distinguish the two distinct histological forms, namely, collagenous colitis and lymphocytic colitis. Presently both forms are diagnosed and treated in the same way; thus the description of the two forms is not of clinical value, though this may change in future. Depending on the patients age and gender 10-30% of patients investigated for chronic diarrhea will be diagnosed with microscopic colitis if biopsies are taken. Microscopic colitis is most common in older patients, especially in female patients and is frequently associated with autoimmune disorders and the consumption of several drugs. This review summarizes the present knowledge of the epidemiology, the pathophysiology, and the diagnosis of microscopic colitis and discusses the former and the present treatment options.
- Atrial arrhythmias in obstructive sleep apnea: underlying mechanisms and implications in the clinical setting. [Journal Article]
- Pulm Med 2013.:426758.
Obstructive sleep apnea (OSA) is a common disorder characterized by repetitive interruption of ventilation during sleep caused by recurrent upper airway collapse, which leads to intermittent hypoxia. The disorder is commonly undiagnosed despite its relationship with substantial cardiovascular morbidity and mortality. Moreover, the effects of the disorder appear to be particularly dangerous in young subjects. In the last decade, substantial clinical evidence has identified OSA as independent risk factor for both bradyarrhythmias and tachyarrhythmias. To date the mechanisms leading to such arrhythmias have not been completely understood. However, recent data from animal models and new molecular analyses have increased our knowledge of the field, which might lead to future improvement in current therapeutic strategies mainly based on continuous positive airway pressure. This paper aims at providing readers a brief and specific revision of current knowledge about the mechanisms underlying atrial arrhythmias in OSA and their clinical and therapeutic implications.
