Corticosteroid treatment in the management of idiopathic granulomatous mastitis to avoid unnecessary surgery.

PURPOSE: Idiopathic granulomatous mastitis (IGM) is a rare benign inflammatory disease of the breast. It can mimic breast carcinoma clinically and radiologically, and usually affects females of childbearing age. There is no commonly accepted optimal treatment for IGM. In this study, we present the clinical and histopathological features and outcomes of the therapeutic management of IGM, as well as the clinical course of the disease when patients were treated with oral corticosteroids. METHODS: This retrospective study included 49 of 87 patients who met the required histological criteria for IGM who were followed up between January 2009 and December 2011. All patients had a disease-free follow-up period of at least 6 months. The data regarding the clinical features at presentation, laboratory values and the treatment modalities were obtained from the medical records of the patients. RESULTS: The mean age of the patients was 34.3 ± 4.37 years. Forty patients were treated with prednisolone, five were started on antituberculosis treatment, two received non-steroidal anti-inflammatory drugs, one received antibiotics and one underwent wide excision. All patients who received steroids responded well to the therapy. CONCLUSION: Systemic therapy with corticosteroids is an effective and appropriate treatment option for IGM. It can provide complete disease resolution and prevent recurrence in the long term. A multidisciplinary approach including specialists in the fields of both general surgery and infectious diseases is essential for the diagnosis, treatment and follow-up of IGM.

Heterotopic ossification of the anterior abdominal wall.

Heterotopic ossification (HO) is a bone formation in a tissue other than the skeletal system. It is more often seen as a complication of orthopedic surgery; however, it is a pathological condition that might be observed during the healing process of abdominal incisions in the midline. The aim of this study is to present a case of a 63-year-old male patient with the complaints of induration and pain on the region of his previous incision through which he had been operated for achalasia. HO is also discussed in the light of the current literature.

The Effect of Adipose-Derived Stromal Vascular Fraction Cells to Abdominal Wall Fascia Defects in Rats: An Experimental Study.

OBJECTIVE: Various synthetic and biological meshes have been developed to reduce recurrence and complications in ventral incisional hernia repairs. Adipose tissue is a rich reserve for mesenchymal stromal cells. In the present study we aimed to examine the effects of adipose-derived mesenchymal stromal cells (AD-MSCs) on abdominal incisional hernia repairs in rats. MATERIALS AND METHODS: The study involved 32 male Wistar-Albino rats, weighing 200-250 g, which were divided into three groups. In Group 1 (control group) only an incisional hernia model was created. In Group 2, the incisional hernia model was created and 1 ml stromal vascular fraction (SVF), obtained from inguinal lipectomy material and containing mesenchymal stromal cells, was injected into the edges of the defect in the same session. In Group 3, only the incisional hernia model was created in the first stage and after 14 days, 1 ml of SVF was injected into the edges of the defect. Skin incisions of rats in Group 1 and 2 were opened on postoperative day 28 while in group 3 were opened on day 42. Peritoneal formation in abdominal wall defect was evaluated macroscopically and histopathologically. RESULTS: Peritoneal formation was significantly superior in Groups 2 and 3 than in Group 1 (p: 0.031). In histopathological evaluation, the structural distortion and polymorphonuclear leukocyte (PMNL) levels were significantly higher in Group 1 than in Group 3 (p: 0.048 and p: 0.046, respectively). Granulation, capillary density, fibrosis and collagen organization were higher in Group 2 and 3, however this difference was not statistically significant (p > 0.05). CONCLUSIONS: Adipose-derived stromal vascular fraction cells obtained from inguinal lipectomy material in rats positively affect the repair of abdominal incisional hernias by increasing peritoneal formation, and reducing structural distortion and PMNL infiltration.

Heterotopic ossification of the anterior abdominal wall.

Heterotopic ossification is the formation of bone tissues in areas other than the skeletal system. It is more often seen as a complication of orthopedic surgery; however, it is a pathological condition that might be observed during the healing of abdominal incisions in the midline. The aim of this study is to present a case of a 63-year-old male patient with complaints of induration and pain on the region of his previous incision through which he had been operated for achalasia. Heterotopic ossification has also been discussed in the light of the current literature.

Pelvic actinomycosis presenting as a malignant pelvic mass: a case report.

INTRODUCTION: Pelvic actinomycosis constitutes 3% of all human actinomycosis infections. It is usually insidious, and is often mistaken for other conditions such as diverticulitis, abscesses, inflammatory bowel disease and malignant tumors, presenting a diagnostic challenge pre-operatively; it is identified post-operatively in most cases. Here we present a case that presented as pelvic malignancy and was diagnosed as pelvic actinomycosis post-operatively. CASE PRESENTATION: A 48-year-old Caucasian Turkish woman presented to our clinic with a three-month history of abdominal pain, weight loss and difficulty in defecation. She had used an intra-uterine device for 16 years, however it had recently been removed. The rectosigmoidoscopy revealed narrowing of the lumen at 12 cm due to a mass lesion either in the wall or due to an extrinsic lesion that prevented the passage of the endoscope. On examination, there was no gynecological pathology. Magnetic resonance imaging showed a mass, measuring 5.5 × 4 cm attached to the rectum posterior to the uterus. The ureter on that side was dilated. Surgically there was a pelvic mass adhered to the rectum and uterine adnexes, measuring 10 × 12 cm. It originated from uterine adnexes, particularly ones from the left side and formed a conglomerated mass with the uterus and nearby organs; the left ureter was also dilated due to the pelvic mass. Because of concomitant tubal abscess formation and difficulty in dissection planes, total abdominal hysterectomy and bilateral salphingo-oophorectomy was performed (our patient was 48 years old and had completed her childbearing period). The cytology revealed inflammatory cells with aggregates of Actinomyces. Penicillin therapy was given for six months without any complication. CONCLUSIONS: Pelvic actinomycosis should always be considered in patients with a pelvic mass especially in ones using intra-uterine devices, and who have a history of appendectomy, tonsillectomy or dental infection. Surgeons should be aware of this infection in order to avoid excessive surgical procedures.

[One of our pioneer women surgeons, Nermin Ünalan Berkan]. / Ilk bayan cerrahlarimizdan Op.Dr. Nermin Ünalan Berkan.

Nermin Ünalan was born in 1922 in Izmir. Her family moved to Istanbul after her birth. Her father was a medical doctor. When she decided to study medicine, her father warned her about the difficulties of the profession. After her graduation from the medical school, she wanted to be a general surgeon, and her father warned her again. However, as she was so determined, he took her to the General Surgery Department of Istanbul Medical Faculty. With not to marry during residency--she was accepted. In 8 January, 1951 she became a general surgeon. She worked in Bilecik, than in Istanbul in different hospitals. She married in 1956, has a son. She retired in 1982. She lives in Istanbul.

Partial fistulotomy and modified cutting seton procedure in the treatment of high extrasphincteric perianal fistulae.

AIM: In our prospective study the method of partial distal fistulotomy and modified cutting seton for high extrasphincteric perianal fistulae is discussed. METHODS: 10 patients (9 males and 1 female) with high extrasphincteric perianal fistulae were treated with partial distal fistulotomy and modified cutting seton. Four or five threads were introduced through the tract; one was tied tightly at the end of the operation, others were tightened every 10th day. While the tied thread cut the tissue, the others drained the tract. The follow-up period ranged from 3 months to 9 years. RESULTS: None of the patients developed major fecal incontinence. 2 of the 10 patients complained of incontinence due to flatus. CONCLUSION: Distal fistulotomy and modified cutting seton can be used in perianal fistulae with high anal or rectal opening, because it combines the effects of both cutting and loose setons and because the postoperative results regarding continence are satisfactory.

Primitive neuroectodermal tumor of the pancreas. A case report of an extremely rare tumor.

Primitive neuroectodermal tumor (PNET) of the pancreas is extremely rare. Although the diagnosis of PNET is suggested by the light microscopic appearance of the tumor, it should be confirmed by the immunohistochemical evaluation of the c-myc expression and if possible, further determination of the particular chromosome translocation, t(11;22)(q24,q12). In this report, we present a male patient with pancreatic PPNET who had been followed up for 50 months. The related literature is also reviewed. In our case, the pathologic diagnosis was based on the positive immunoreactivity for CD99 in many of the tumor cells. The complementary cytogenetic studies were not possible in the private setting of the patient's treatment. The patient was 31 years old when first operated. Within 4 months of the first operation he had local recurrence. In the third year of his follow-up he had been discovered to have pulmonary metastases and another metastatic tumor in his lung was diagnosed the year after. The metastatic foci were primarily treated by surgical resections. He had chemotherapy after each resection of pulmonary metastatic foci. After 50 months of the initial surgical intervention, he succumbed to widespread thoracic and bone metastases. Because of the extreme rarity of PPNET in the pancreas, and its rather protracted course, we think our case may further contribute to the ever expanding database for this particular entity.
