The authors describe two cases of malignant non-Hodgkin's lymphoma in a mammary site observed at IRCCS Policlinico San Matteo (Pavia). Histologic, immunohistochemical and clinical features are illustrated. Correct diagnosis is essential so that appropriate multidisciplinary treatment may be applied.
The authors report a retrospective study of four patients treated for sigmoid volvulus at the Clinica Chirurgica II of IRCCS Policlinico S. Matteo of Pavia between April 1974 and June 1989. They are collected from a series of 74 consecutive operations for colonic obstruction not related to hernias of the inguinal-crural region (incidence 5.4%). One patient died. The authors review the incidence, epidemiology, etiopathogenetic hypothesis, clinical patterns, nonoperative and operative therapeutic options of the affection. They emphasize the poor prognosis because the sigmoid volvulus usually occurs in elderly ill patients.
The Authors report a case of epithelial cyst of the spleen-observed in a 25 years old woman. After remembering the nomenclature and pathogenetic hypothesis, they consider clinical patterns of this rare disease of the spleen which is usually found in children and young adults. The Authors discuss pathological findings, diagnostic aids, especially non-invasive imaging. They also suggest considering the cysts in diagnosis of the diseases of the spleen and splenectomy as a treatment of choice.
High-resolution ultrasonography was performed on 55 patients with palpable skin lesions, all submitted to surgical excision and to histologic diagnosis. In all the cases, the ultrasound picture was confirmed by the surgical appearance of the lesions. The sonographic structure was characteristic in the case of cysts and angiomas, lymphangiomas in particular. Ultrasonography is considered a simple and reliable technique for the pre-operative evaluation of skin nodules, as it gives a clear picture of their size, depth, and outline. However, sonography cannot substitute for the clinical dermatologic approach and the need for an histologic diagnosis.

Authors perform a retrospective review of all hepatic injuries operated on between 1974 and 1990 at Clinica Chirurgica II (ex Patologia Chirurgica II, ex Semeiotica Chirurgica) of Policlinico San Matteo (IRCCS) of Pavia. Thirteen patients were treated, 9 men and 4 women, with age ranged from 13 to 68 years and a mean age of 38 years. They were 21% of all patients operated on for abdominal trauma. Penetrating wounds were present in only two cases (15%), the other patients (85%) were affected by blunt trauma. The mechanisms of injuries were: road accidents (77%), fall at work (8%), gun shot wound (8%), stab wound (8%). All patients had associated injuries. The mortality was 31%: one patient died for haemorrhagic shock and the other three for craniocerebral injuries. After reviewing the several haemostatic techniques advocated for the various types of hepatic injuries, the authors stress that, although most lesions are minor and can be managed by simple technique of haemostasis, often the prognosis is severe for the associated injuries.
Authors refer about their experience on 12 cases of male breast carcinoma (MBC), studied in years 1975-1985 at the Semeiotica Chirurgica e Patologia Chirurgica II dell'I.R.C.C.S. Policlinico S. Matteo of Pavia. After a thorough discussion of the etiopathologic factors, there are cited the most common histotypes of MBC, as well as the typical clinical aspects, of basic importance for the compilation of the diagnostic inquiry, which, in uncertainty, makes use of the acuaspiration and of the excisional biopsy, there is referred on the present therapeutic trends, and results of their casuistry are exposed.
Colo-rectal endometriosis involving extensive intestinal wall may result in obstruction. This report is based on two patients having symptomatic intestinal endometriosis that required operative treatment. Diagnostic, pathologic and therapeutic findings were reviewed. Current treatment is the removal of the endometriomas, while removal of the reproductive organs should be made only after evaluation on the patient's menstrual status, age and future pregnancy desire.
The authors report a retrospective review of four cases of gallstone ileus seen at Semeiotica Chirurgica, at Patologia Chirurgica II and Clinica Chirurgica II of Policlinico San Matteo I.R.C.C.S. of Pavia between 1974 and 1989. Three patients were women and one male, with average age 69.4 years. All obstructions occurred in the distal ileum. Proceeding from available data in the literature and from their personal experience the Authors emphasize that gallstone ileus is a rare cause of mechanical obstruction of intestine (4% of the obstructions of the small bowel). This disease usually occurs in elderly women, with concomitant illness. Approximately 50 per cent of the patients have an history of gallbladder disease. The authors discuss the controversy on performing an enterolithotomy alone versus one stage procedure consisting of removal of the impacted stone, fistula repair and cholecystectomy. The prognosis is severe. High mortality and many postoperative complications are caused by the advanced age of the patients, concomitant illness and usually delayed diagnosis.
The authors describe a case of splenic cyst recently observed. After remembering the nomenclature and pathogenetic hypothesis, they consider clinical patterns and emphasize pathological findings, diagnostic aids, especially noninvasive imaging. Authors discuss why the cyst was probably hydatid one, although histologic examination did not show scolices, and believe that the treatment of choice is splenectomy.
The Authors report 4 cases of Ogilvie's syndrome come to their observation during the last 5 years by the clinical surgery II of the I.R.C.C.S. Polyclinic "San Matteo" of Pavia. Remembering the infrequency of the affection and the controversial etiopathogenesis theories, the Authors study the clinical picture and the diagnostic problems, pointing out how some researches, especially radiological and endoscopical, permit to obtain a therapeutic solution of the syndrome. They underline the colonic perforation risk, certainly overestimated, and they show the therapeutic, medical or surgical, orientations, according to the evolution of the illness, the anatomic situations and the general conditions of the patient.
