Background: Mastectomy is the recommended treatment for ipsilateral breast tumor recurrence (IBTR) in patients who initially received breast conservation surgery (BCS) and radiation. We evaluated the 3 types of mastectomies performed for the surgical treatment of IBTR (nipple sparing (NSM), skin sparing (SSM) and total mastectomy (TM)) to assess surgical complications and local control outcomes among groups.
Methods: Patients who developed IBTR after BCS and received mastectomy from 2011 to 2019 were reviewed. Patient characteristics and treatment were analyzed. The incidence of postoperative complications and second breast cancer recurrence were compared.
Results: Mastectomy was performed in 113 patients presenting with isolated IBTR (17 NSM, 48 SSM and 48 TM). There was no difference in post-operative complications between groups. At 3-year follow-up, 5 (4%) patients had a second recurrence. Tumor size at IBTR was the only predictor for second recurrence and not mastectomy type or receipt of reconstruction.
Conclusion: In patients initially treated with BCS who experienced an IBTR, NSM or SSM mastectomy with immediate reconstruction had low complication rates and no increase in local recurrence compared to the TM group.

Hidradenocarcinoma (HAC) is a rare neoplasm that typically occurs in the head and neck region but seldom affects the chest wall. Histopathology and immunohistochemistry remain essential for diagnosing HAC, although their clinical utility in determining metastasis can be limited. Given the pathological rarity and histopathological heterogeneity of HAC, we report a case demonstrating the utility of positron emission tomography/computed tomography (PET/CT) combined with immunohistochemical examination for the accurate diagnosis and staging of HAC.

Background: Ectopic pregnancy, occurring outside the uterine cavity, poses a significant health risk, with Fallopian tube involvement being predominant. Recurrent ectopic pregnancy, particularly in the ipsilateral remnant of a previously removed tube, is a rare and poorly understood phenomenon. Here, we present a case of recurrent ectopic pregnancy occurring in the distal remnant of the right fallopian tube following ipsilateral incomplete salpingectomy in a 22-year-old woman.

Objective: Peripheral nerve injury results in functional alterations of the corresponding active brain areas, which are closely related to functional recovery. Whether such functional plasticity induces relative anatomical structural changes remains to be investigated.
Methods: In this study, we investigated the changes in brain cortical thickness in patients with facial paralysis following neurorrhaphy treatment at different follow-up times.
This case report describes a unique presentation of May-Thurner syndrome (MTS) in a 28-year-old woman, characterized by the congenital bifurcation of the left common iliac vein (LCIV) into the outer (OLCIV) and inner (ILCIV) segments. Both veins experienced significant compression - OLCIV proximally and ILCIV medially - due to the overlying right common iliac artery (RCIA) and lumbar spine. The patient presented with bilateral spider veins, lower extremity swelling, pelvic discomfort, and bilateral leg cramping.

Objective: Varicose vein ablation is generally indicated in patients with active/healed venous ulcers. However, patient selection for intervention in individuals without venous ulcers is less clear. Tools that predict lack of clinical improvement (LCI) following vein ablation may help guide clinical decision-making but remain limited.
