Reconstruction of Bilateral Upper and Lower Eyelid Ectropion Caused by a Liquid Unblocker Chemical Burn.

Liquid drain unblockers, although meant to be used by professionals with protective equipment, are sometimes used in the household without any precautions. This could lead to severe chemical burns, as in the case we present with severe eyelid ectropion. This study aims to stress the need for preventive measures regarding the use of chemicals and for close observation and timely surgical intervention in chemical burn patients to prevent and limit disfigurement. A 45-year-old woman was injured while using an unblocker (90% sulfuric acid) at home. Accidentally, a quantity of the liquid was spilled on her face. She was initially examined in ophthalmology emergencies because of the obvious ocular involvement, and the cutaneous component was underestimated. On the third post-burn day, she was referred as an outpatient to our clinic, and because of the soft consistency and patchy pattern of the burn, she was asked to revisit in a week. Unfortunately, she reappeared two months post-burn with severe ectropion of all four eyelids and a high risk of corneal abrasion, desiccation, and further damage to the already injured left eye as well as the right eye. She underwent three operations in six months and a fourth 15 months after the accident, with the release of the scarred eyelids with full-thickness skin grafts, Z-plasties, and V-Y plasties. After four operations and sessions of triamcinolone acetonide intralesional injection, the patient has a satisfactory eyelid position and function with adequate closure and scar maturation. Domestic use of strong industrial chemicals is dangerous, and public education for prevention is urgently needed. On the other hand, it is mandatory to follow up very closely with chemical burn patients to prevent severe sequelae, especially in the delicate and contraction-prone periocular and perioral areas. Reconstruction, in these cases, is a complex task. Often, several surgeries are needed to restore acceptable function and appearance. Burn disfigurement and self-stigma will follow the patients to some extent throughout their lives.

Giant Pilomatrix Carcinoma of the Thorax: An Uncommon and Clinically Misdiagnosed Tumor.

Pilomatrix carcinoma is an unusual and aggressive malignant tumor deriving from follicular matrix cells and exhibiting a metastatic potential to lungs and regional lymph nodes in 10% of cases. We report the case of a 54-year-old male patient who presented with a biopsy-proven malignant pilomatrixoma of the thoracic region, which recurred multiple times after previous excisions. Due to the size of the tumor (28 by 22 cm), wide excision and axillary lymphadenectomy of levels I and II were performed, followed by reconstruction with a free deep inferior epigastric artery perforator flap and adjuvant radiotherapy. Owing to its rarity, this tumor can initially be misdiagnosed, resulting in delayed treatment and recurrences if inadequately excised. Also, large tumor size is correlated with a higher incidence of metastasis. High index of clinical suspicion and wide excision are recommended, along with the need of establishing oncological guidelines for better prognosis.

Wrist and hand degloved injuries salvaged with reverse radial forearm flap in the CoVid-19 era.

Reverse radial forearm flap is a quick and reliable flap, providing a well-vascularized tissue for coverage of hand defects. It is based on the reverse flow of the radial artery and the only drawback is the proximal ligation of the vessel. Two cases with complex dorsal hand defects were referred with delay to our Hand Unit, due to the CoVid-19 pandemic restrictions. In both cases deep structures of the wrist and fingers were exposed and the wounds were infected. Surgical debridement, skin coverage and reconstruction were decided in a staged approach: The reverse radial forearm flap was first performed, and in subsequent stages, functional restoration with hamstrings tendon grafts and finger joints arthrodesis successfully followed. These two cases highlight the reliability of a traditional pedicled flap in the salvage of complex hand defects, especially when time and resources are limited due to a pandemic.

Facial skin metastasis due to small-cell lung cancer: a case report.

INTRODUCTION: Cutaneous metastases in the facial region occur in less than 0.5% of patients with metastatic cancer. They are an important finding and are not often the first sign leading to diagnosis. CASE PRESENTATION: We describe the case of a 64-year-old male patient who presented with dyspnea, pleuritic pain, loss of weight and a nodule on his left cheek. A chest X-ray revealed a left upper lobe mass with mediastinal lymphadenopathy. Excision biopsy of the facial nodule revealed small-cell lung carcinoma. Palliative chemo-radiotherapy was administered and the patient survived for 12 months. CONCLUSION: A high index of suspicion is necessary for the early detection of facial cutaneous metastases. Appropriate treatment may prolong patient survival.
