RESUMEN
INTRODUCTION: Leiomyomatosis peritonealis disseminata (LPD) is an uncommon disease featured by the presence of multiple nodules of smooth muscle cells scattered in the abdominal cavity. To date only about 150 cases have been reported in literature. We report a case of recurrent LPD after laparotomy. CASE PRESENTATION: In March 2016 a 36-year-old female, with a history of multiple previous laparoscopic myomectomies, consulted her gynaecologist complaining abdominal pain; a MRI was performed and reported multiple pelvic masses, subsequently excised during laparotomy. The patient refused a total hysterectomy with bilateral salpingo-oopherectomy so a close follow-up was recommended. In November 2017 when a new MRI revealed recurrency of the disease, a second laparotomy is performed and all visible nodules are excised. The histological exam confirms LPD diagnosis. On follow-up after three months the patients is completely asymptomatic. DISCUSSION: Differential diagnosis of LPD is challenging due to its similarity to carcinomatosis and to other benign abdominal disorders. Malignant transformation is rare, but it may occur, so a close follow-up is necessary. Even if there is no consensus regarding the treatment, hormonal therapy is probably the best first line approach, while surgery should be the second choice. CONCLUSIONS: LPD is an uncommon but potentially severe disease. In our opinion larger studies are necessary to improve our diagnostic effectiveness and to define the best therapeutic strategy.
RESUMEN
Sentinel lymph node biopsy for ductal carcinoma in situ (DCIS) of the breast is not standard of care. However, nodal involvement for DCIS patients is reported. Aim of our study was to identify preoperative features predictive of nodal involvement in DCIS patients. We have retrospectively reviewed 175 patients with a preoperative diagnosis of DCIS following a vacuum-assisted breast biopsy, and undergoing surgery with sentinel node biopsy. Variables distribution was compared between patients upstaged to invasive cancer at final pathology and patients with a confirmed DCIS, and between positive vs negative sentinel node patients. Univariate and multivariate analyses were performed for risk of a positive node. Lymph node biopsy was positive in 13 (7.4%) patients, with 8 (61.5%) macrometastases and 5 (38.5%) micrometastases. In these patients, Breast Imaging Reporting and Data System (BI-RADS) index >4 (OR 4.69, 95% CI 1.282-17.224, P = .02), lesion extension ≥20 mm (OR 4.25, 95% CI 1.255-14.447, P = .02), multifocal disease (OR 4.12, 95% CI 0.987-17.174, P = .05), comedo type (OR 3.54, 95% CI 1.044-11.969, P = .04), and upstaging (OR 4.56, 95% CI 1.080-19.249, P = .04) were all predictive of nodal involvement, although upstaging could not be predicted preoperatively. By multivariate analysis, the only independent factor predictive for positive sentinel node was multifocal disease (OR 5.14, 95% CI 1.015-26.066, P < .05). A preoperative diagnosis of DCIS, also including advanced biopsy systems such as vacuum-assisted breast biopsy, may be not always sufficient to exclude patients from sentinel node biopsy. DCIS patients with associated BI-RADS >4, lesion extension ≥20 mm, comedo type, and above all multifocal disease should be considered for axillary evaluation.

AIM: This study aimed to evaluate the benefits of Arnica montana on post-operative blood loss and seroma production in women undergoing unilateral total mastectomy by administering Arnica Montana 1000 Korsakovian dilution (1000 K). MATERIALS AND METHODS: From 2012 to 2014, 53 women were randomly assigned to A. montana or placebo and were followed up for 5 days. The main end point was the reduction in blood and serum volumes collected in drainages. Secondary end points were duration of drainage, a self-evaluation of pain, and the presence of bruising or hematomas. RESULTS: The per-protocol analysis revealed a lower mean volume of blood and serum collected in drainages with A. montana (-94.40 ml; 95% confidence interval [CI]: 22.48-211.28; P = 0.11). A regression model including treatment, volume collected in the drainage on the day of surgery, and patient weight showed a statistically significant difference in favor of A. montana (-106.28 ml; 95% CI: 9.45-203.11; P = 0.03). Volumes collected on the day of surgery and the following days were significantly lower with A. montana at days 2 (P = 0.033) and 3 (P = 0.0223). Secondary end points have not revealed significant differences. CONCLUSIONS: A. montana 1000 K could reduce post-operative blood and seroma collection in women undergoing unilateral total mastectomy. Larger studies are needed with different dilutions of A. montana to further validate these data.
RESUMEN
Hidradenocarcinoma is an uncommon malignant intradermal tumor of sweat gland origin with a predilection for the face and extremities. It is encountered equally in males and females, usually in the second half of life. These tumors tend to be locally aggressive. In our case, the tumor was located relatively superficially but without any apparent connection to the overlying skin. The typical disease course includes local and sometimes multiple recurrences, and some patients develop regional lymph node and distant metastases. These type of tumors in the parenchyma of the breast are extremely rare. We report a case of hidradenocarcinoma in a 77-year-old woman who presented with a palpable inflammatory nodule in the right breast.
