Breast hamartoma is an uncommon poorly recognised benign breast neoplasm. Hamartoma displaying marked smooth muscle components known as myoid hamartoma of the breast is a much rarer entity. We present a case of myoid hamartoma of breast with chondroid differentiation in a 46-year-old woman. The painless breast lump was circumscribed and mammography showed a well-encapsulated large, dense mass with no calcification. Core needle biopsy was reported as fibroadenoma. The lesion was excised. Microscopically, it composed of many groups of mammary glandular components with dense fibrous stroma, adipose tissue and marked groups of smooth muscle fibres. Foci of chondroid differentiation were noted in the lesion. The smooth muscle cells showed strong and diffuse immunoreactivity for vimentin, myogloblin, alpha-smooth muscle actin, desmin and CD34 and failed to express pan-cytokeratin or S100 protein. The ducts lined by epithelial cells were reactive to pan-cytokeratin while the myoepithelial cells were reactive to S100 protein. The various immuno-histochemical staining as well as the cyto-histological changes encountered in myoid hamartomas are discussed with clinical, radiological and pathological correlation to differentiate it from other benign and malignant breast lesions.

Percutaneous nephrostomy is relatively safe for temporary urinary diversion. However, colonic perforation due to percutaneous nephrostomy can happen with an incidence of 0.2% as reported in the English literatures. To our knowledge, this is the first case being reported as a complication following treatment for traumatic renal injury. This paper is to share our treatment approach which differs from the usual approach according to existing literatures. We report on a young man who sustained grade IV renal injury due to blunt trauma and was managed conservatively. The treatment of traumatic renal injury via urinary diversion was complicated with an iatrogenic colonic perforation. The management and subsequent treatment of this patient is discussed in this case report.

Blunt traumatic tracheobronchial injury is rare, but can be potentially life-threatening. It accounts for only 0.5%-2% of all trauma cases. Patients may present with non-specific signs and symptoms, requiring a high index of suspicion with accurate diagnosis and prompt treatment. A 26-year-old female was brought into the emergency department after sustained a blunt trauma to the chest from a high impact motor vehicle accident. She presented with signs of respiratory distress and extensive subcutaneous emphysema from the chest up to the neck. Her airway was secured and chest drain was inserted for right sided pneumothorax. CT of the neck and thorax revealed a collapsed right middle lung lobe with a massive pneumothorax, raising the suspicion of a right middle lobe bronchus injury. Diagnosis was confirmed by bronchoscopy. In view of the difficulty in maintaining her ventilation and persistent pneumothorax with a massive air leak, immediate right thoracotomy via posterolateral approach was performed. The right middle lobar bronchus tear was repaired. There were no intra- or post-operative complications. She made an uneventful recovery. She was asymptomatic at her first month follow-up. A repeated chest X-ray showed expanded lungs. Details of the case including clinical presentation, imaging and management were discussed with an emphasis on the early uses of bronchoscopy in case of suspected blunt traumatic tracheobronchial injury. A review of the current literature of tracheobronchial injury management was presented.

Malaysia has one of the highest total numbers of COVID-19 infections amongst the Southeast Asian nations, which led to the enforcements of the Malaysian "Movement Control Order" to prohibit disease transmission. The overwhelming increasing amount of infections has led to a major strain on major healthcare services. This leads to shortages in hospital beds, ventilators and critical personnel protective equipment. This article focuses on the critical adaptations from a general surgery department in Malaysia which is part of a Malaysian tertiary hospital that treats COVID-19 cases. The core highlights of these strategies enforced during this pandemic are: (1) surgery ward and clinic decongestions; (2) deferment of elective surgeries; (3) restructuring of medical personnel work force; (4) utilization of online applications for tele-communication; (5) operating room (OR) adjustments and patient screening; and (6) continuing medical education and updating practices in context to COVID-19. These adaptations were important for the continuation of emergency surgery services, preventing transmission of COVID-19 amongst healthcare workers and optimization of medical personnel work force in times of a global pandemic. In addition, an early analysis on the impact of COVID-19 pandemic and lockdown measures in Malaysia towards the reduction in total number of elective/emergent/trauma surgeries performed is described in this article.
