  • Presently, the world population of the elderly is growing. By improving health hygiene and welfare indicators, mortality and birth rates decrease and life expectancy increases, making the present century the century of elderly. Aging is one of the main risk factors for development of cancer, which itself is the second cause of death in old people. This study was conducted to assess the prevalence of cancer in the elderly covered by the Islamic Republic of Iran Broadcasting (IRIB) insurance program and to obtain suitable programs for cancer screening and early detection, increase patient survival, improve elderly care and to reclaim the cost of treatment in comparison to the national and international statistics. This is a cross-sectional study conducted on all elderly patients diagnosed with malignancy based on their pathology reports. In this study, of the total 75,500 patients covered by IRIB insurance, 17.2% belonged to the elderly group, males accounting for 53.3%. The most common cancers in old men were prostatic cancer (61.3%), colon cancer (10.3%) cancer of the hematologic system, bladder cancer (9.6%), lung cancer (9.1%), thyroid cancer (3.9%) and brain tumors (1.3%). In the elderly women, the most common cancers were breast cancer (80.1%), colon cancer (5.1%), thyroid cancers (4.4%), bladder and hematologic system malignancies (3.6), lung cancer (2.9%) and brain tumors (0.7%). In addition, the prevalence of cancer was almost the same as national and international statistics. With the exception of non-melanoma skin cancer no difference was shown in prevalence of cancer between IRIB elderly patients and the other groups of cancer patients in Iran.

  • Acute graft-versus-host-disease (GVHD) is characterized by selective damage to the liver, the skin, and the gastrointestinal tract. Following allogeneic hematopoietic stem cell transplantation, donor bone marrow (BM) cells repopulate the immune system of the recipient. We previously demonstrated that the acute intestinal GVHD (iGVHD) mortality rate was higher in MyD88-deficient BM recipients than that in the control BM recipients. In the present study, the role of MyD88 (expressed by donor BM) in the pathophysiology of hepatic GVHD (hGVHD) was examined. Unlike iGVHD, transplantation with MyD88-deficient T-cell depleted (TCD) BM attenuated hGVHD severity and was associated with low infiltration of T cells into the liver of the recipients. Moreover, GVHD hosts, transplanted with MyD88-deficient TCD BM, exhibited markedly reduced expansion of $CD11b^+Gr-1^+$ myeloidderived suppressor cells (MDSC) in the liver. Adoptive injection of the MDSC from wild type mice, but not MyD88-deficient mice, enhanced hepatic T cell infiltration in the MyD88-deficient TCD BM recipients. Pre-treatment of BM donors with LPS increased MDSC levels in the liver of allogeneic wild type BM recipients. In conclusion, hGVHD and iGVHD may occur through various mechanisms based on the presence of MyD88 in the non-T cell compartment of the allograft.

  • Henoch-Sch$\ddot{o}$nlein 자반병 신염과 유사한 증상을 가지는 10세 여자에게 발생한 급격한 신기능 저하를 동반하지 않은 현미경적 다발혈관염 1례를 경험하였기에 보고하는 바이다. 이 혈관염의 경우. 진단 시점 또는 치료 시작할 때의 신장기능 저하가 심할수록 병의 예후가 나쁘므로[20], 사구체 여과율이 떨어지기 전에 빠른 진단과 치료가 필요하다. Henoch-Sch$\ddot{o}$nlein 자반병이 의심될 경우 단백뇨와 혈뇨가 지속되면, 다른 혈관염과의 감별을 위해 ANCA, 신장 조직검사가 도움을 줄 것으로 생각된다.

  • Nevus comedonicus is a type of hamartoma that arises from a developmental anomaly of the mesodermal part of the pilosebaceous gland. In most cases of nevus comedonicus, an acne-like skin condition develops. Repeated inflammation can cause a morphological change to the cyst, papule, to abscess. We experienced a case of congenital nevus comedonicus, which led to the formation of large multiple cysts. A 50-year-old man was referred with a $12.5{\times}10cm$ lobulated mass on the posterior neck and upper back. The patient had a widespread presence of nevus comedonicus in the region ranging from the right superior chest to the posterior neck. The patient had a 30-year history of six prior excisions. A magnetic resonance imaging review led to a diagnosis of nevus comedonicus. Surgical treatment consisted of excision of the mass and wide excision for the patch type of nevus comedonicus around the neck. On histopathology, multiple masses were diagnosed as typical cysts containing keratinized tissue. The diffuse comedone lesions were diagnosed as nevus comedonicus. This case shows that large, multiple cysts can occur as a long-term complication of nevus comedonicus, and also highlights the importance of radical resection to prevent its further invagination.

  • Lymphedema is a chronic disorder characterized by lymph stasis in the subcutaneous tissue. Lymphatic fluid contains several components including hyaluronic acid and has many important properties. Over the past few years, significant research has been performed to identify an ideal tissue to implant as a filler. Because of its unique composition, fat harvested from the lymphedema tissue is an interesting topic for investigation and has significant potential for application as a filler, particularly in facial rejuvenation. Over a 36-month period, we treated and assessed 8 patients with lymphedematous limbs who concurrently underwent facial rejuvenation with lymphedema fat (LF). We conducted a pre- and postoperative satisfaction questionnaire survey and a histological assessment of the harvested LF fat. The overall mean general appearance score at an average of 6 months after the procedure was $7.2{\pm}0.5$, demonstrating great improvement. Patients reported significant improvement in their skin texture with a reading of $8.5{\pm}0.7$ and an improvement in their self-esteem. This study demonstrates that LF as an ideal autologous injectable filler is clinically applicable and easily available in patients with lymphedema. We recommend the further study and clinical use of this tissue as it exhibits important properties and qualities for future applications and research.

  • Small cell carcinoma mainly occurs in the lung. Approximately 2.5-5% of small cell carcinomas are primary extrapulmonary which are commonly found in the esophagus, GI tract, skin, uterus, and urinary tract. Small cell carcinoma of the head and neck is extremely rare and its prognosis is poor. We report a case of supraglottic small cell carcinoma with cervical lymph node and rib metastasis in a 75-year-old man. The patient was treated with sequential combination of chemotherapy and radiotherapy, but the cancer has progressed. We concluded that we have to find an effective therapy for laryngeal small cell carcinoma.

  • Verruciform xanthoma (VX) is a rare, benign lesion that presents in the oral cavity, skin, or genital organs as a verrucous, papillomatous, or flat papule with varying colors. VX has indistinct clinical features, making histopathological examination necessary for a definitive diagnosis. Histologically, VX is characterized by parakeratosis, rete ridges with uniform depth, and an accumulation of the foam cells, which are also known as the "xanthoma cells". These foam cells test positive for antibodies, such as CD-68 and vimentin; it is thought that VX foam cells are derived from the monocyte-macrophage lineage, and that VX's pathogenic mechanism is partly related to an immune mechanism. Nevertheless, the pathogenesis of VX remains unclear. VX can be treated by surgical excision; other medical, chemical, and radiological treatments are not required postoperatively. Recurrence and malignant transformation of VX are rare. Two patients, each with a mass of unknown origin on the palatal gingiva, were presented at our clinic. Excisional biopsies of the masses were performed for a histological diagnosis after clinical and radiological examinations. Histological examination confirmed a diagnosis of VX in both cases.
