Abstract

Introduction and importance: Dermatofibrosarcoma protuberans (DFSP) is a rare soft tissue sarcoma that primarily affects middle-aged adults but can also occur in children. Despite its low metastatic potential, DFSP displays aggressive local behavior and a high rate of local recurrence. Diagnosis in children can be delayed due to confusion with other skin conditions. This case report aims to discuss the case management of dermatofibrosarcoma protuberans in a 13 year old female. Presentation of case: A 13-year-old female patient presented with a progressively enlarging lump on the left eyelid, initially resembling small brown spots that coalesced over 7 months. Intermittent bleeding and pain were reported. Physical examination revealed a dark brown mass in the left frontotemporal region, with solid, non-fragile characteristics. Clinical diagnosis suggested a suspicious malignant skin tumor, confirmed as basal cell carcinoma. Treatment involved wide excision and flap reconstruction. Post-operative care included infusion, antibiotic injection, and pain management. The patient's prognosis was favorable, though functional impairment was possible. Follow-up revealed histopathological findings of pigmented dermatofibrosarcoma protuberans. Discussion: DFSP is a rare but significant malignancy that poses diagnostic challenges due to its varied clinical presentations and histopathological features. While primarily affecting young to middle-aged individuals, it can also manifest in pediatric populations. Diagnosis typically involves histopathological assessment, confirming characteristic spindle cell proliferation with CD34 expression. Surgical excision remains the cornerstone of treatment, complemented by adjuvant therapies like imatinib mesylate or radiation in select cases. Regular surveillance, comprising frequent evaluations in the initial post-excision period followed by yearly monitoring, is imperative for detecting any recurrence or metastasis promptly. Conclusions: The structured approach in DFSP ensures optimal patient management and outcomes. Surgical management with Wide local excision (WLE) or Mohs micrographic surgery (MMS) is the gold standard in the treatment of DFSP.

Abstract

Zebrafish serve as a pivotal model for bioimaging and toxicity assessments; however, the toxicity of banana peel-derived carbon dots in zebrafish has not been previously reported. The aim of this study was to assess the toxicity of carbon dots derived from banana peel in zebrafish, focusing on two types prepared through hydrothermal and pyrolysis methods. Banana peels were synthesized using hydrothermal and pyrolysis techniques and then compared for characteristics, bioimaging ability, and toxicity in zebrafish as an animal model. Pyrolysis-derived banana peel and hydrothermal-derived banana peel showed blue emission under ultraviolet light, indicating excitation-dependent behavior. To test their potential application for bioimaging, a soaking method was used using zebrafish that showed fluorescence intensity in the eyes, abdomen, and tail of zebrafish. Toxicity comparison showed that pyrolysis-derived banana peel had lower toxicity with 50% lethal concentrations (LC50) of 1707.3 ppm than hydrothermal-derived banana peel (LC50 993 ppm) in zebrafish. Both types of carbon dots showed significant differences (p<0.05) in hatching rates at 96 and 120 hours of exposure. Of the two methods for carbon dot synthesis from banana peel, the pyrolysis method had a higher toxicity threshold than the hydrothermal method, as indicated by the LC50 value and the number of zebrafish embryos that died, hatched delayed, and experienced malformation during their development.
