RESUMEN
Acute lithiasic cholecystitis represents one of the most frequent pathologies of the digestive tract, most often requiring emergency surgical treatment. The prevalence of this condition increases with age and it affects women the most. Laparoscopic cholecystectomy is the preferred surgical treatment, as it diminishes postoperatory pain, it reduces the hospitalization period and medical and social costs, and it also provides a rapid postoperatory recovery. We present the case of an elder female patient, who presented with complex symptoms and signs, suggesting both lithiasic cholecystitis and a gallbladder neoplastic condition. Although there was preferred a laparoscopic cholecystectomy, the presence of an inflammatory process with intense sclerous reaction in the hepatocystic triangle led the conversion of laparoscopic cholecystectomy into an open, classical one. Due to the inflammatory process, the common bile duct (CBD) could not be explored. The subsequent practicing of a cholangiography on the drain tube highlighted the presence of an obstacle in the end zone of the CBD, which could not be removed until the second surgical intervention. The histopahological exams - from frozen sections to immunohistochemistry - had a crucial role in deciding patient's surgical management. The good evolution of the case and the final postoperatory result confirmed that the therapeutic manner chosen for this case was the appropriate one.

Chronic venous leg ulcers (VLU), especially long-lasting non-healing ulcers, are among the risk factors for squamous cell carcinoma (SCC). Malignant transformation of a VLU is a rare finding and the relative risk of carcinomatous transformation is quite low (about 5.8). SCC arising in the context of a VLU has a particularly aggressive behavior. A 76-year-old male patient with no relevant medical familial history, with chronic venous insufficiency CEAP C6 for 10 years [recurrent leg ulcers with favorable outcome (healing) after specific local and systemic treatment], showing for about three years one ulcerated lesion located on the anterior upper third of the right calf non-responsive to specific treatment, which subsequently increased their size and merged. Biopsy sample was taken. Histopathology showed epidermal acanthosis, papillomatosis, intense parakeratosis, pseudoepitheliomatous hyperplasia, dysplasia and moderately differentiated squamous cell carcinoma with areas of acantholysis. Immunohistochemistry (Ki67, EMA, cytokeratin 34ßE12 and p63) was performed and all types of immunostaining were moderately to intense positive. Above-knee leg amputation and specific oncologic treatment were proposed as possible curative solutions but the patient refused. Ten months after diagnosis and discharge form the Department of Dermatology, the patient died. Patients with chronic venous leg ulcers and clinically suspicious lesions should be evaluated for malignant transformation of the venous lesion. When diagnosed, malignancy complicating a chronic venous leg ulcer requires a resolute treatment as it may be fatal.
