RESUMEN

Malignant transformation of chronic burn scars are usually toward cutaneous lineages, including squamous cell carcinoma, basal cell carcinoma, and malignant melanoma. Sarcomas are less common. Undifferentiated pleomorphic sarcoma(UPS) is a subtype of soft tissue sarcoma with storiform-pleomorphic cells of uncertain origin, and has sparingly been reported to arise from burn scars. The majority are localized lesions probably due to the spatial distance of mesenchymal cells from the epithelium. The authors describe a rare case of UPS of the chronic burn scar of his knee with ipsilateral femoral and external iliac lymph node metastasis.

RESUMEN

Kienböck disease, a rare disease that can cause chronic pain and motor dysfunction, occurs due to avascular necrosis of the lunate bone, which leads to dislocation of the carpal bone. Among various other etiologies, Kienböck disease can cause closed tendon rupture of the finger. In this report, we introduce a case of total rupture of the second extensor digitorum communis and the extensor indicis proprius tendons caused by undiagnosed Kienböck disease in an elderly female patient.

RESUMEN

Angiolymphoid hyperplasia with eosinophilia (ALHE) is a rare benign vascular tumor. The pathogenesis of ALHE is unknown; however, it may be linked to local trauma. ALHE predominantly occurs in areas of the preauricular region, forehead, and scalp; the masseter area is rarely involved. A 49-year-old man was referred for a mass in the right cheek region that was felt 2 months prior. Physical and imaging examination results suggested the presence of a benign tumor. Thus, surgical excision was performed. Pathologic findings confirmed an unexpected diagnosis of ALHE. This case was interesting, since the mass occurred at an unusual site with a misdiagnosis of an epidermal inclusion cyst.

RESUMEN

Isolated fracture of maxillary sinus anterior wall is relatively uncommon. If the extent of fracture is minimal, only conservative care is amenable, however, there is no agreement on whether infraorbital nerve dysfunction can be used as an indication for surgical intervention. This study was conducted to verify the effect of decompression surgery of infraorbital foramen for recovery of hypoesthesia. A total of 26 patients with unilateral fracture of maxillary sinus anterior wall were enrolled. Ten who received only conservative therapy were allocated in the control group, while sixteen patients were assigned to the decompression group. Pre- and post-treatment sensory assessment using visual analogue scale (VAS) was recorded. Overall treatment satisfaction was also evaluated by means of global assessment scale (GAS). Both absolute VAS value and score increment showed statistical difference only at 4 weeks (P = 0.010 and P = 0.021, respectively), but no significant difference at 1, 12, and 24 weeks. GAS score also showed no statistical significance (P = 0.386). Decompression surgery of infraorbital foramen does not have a significant effect on hypoesthesia recovery in isolated fracture of maxillary sinus anterior wall. Therefore, it is not recommended to perform the operation when the infraorbital nerve hypoesthesia is the only indication for the open reduction.
