Mammary hamartoma.

INTRODUCTION: Mammary hamartomas are rare benign breast lumps. They are usually painless, wellcircumscribed, mobile and with no adherence to skin or muscle, composed of varying amounts of fat, glandular and fibrous tissue. Mammary hamartoma has been classically considered as an underdiagnosed pathology, but with the increasing use of diagnostic procedures in breast tumours, the number of hamartomas has increased in the last years. Because there is no distinct pathological feature, a correlation with the clinical findings and image techniques is necessary in order to achieve a correct diagnosis of the pathology. MATERIALS AND METHODS: The clinicopathological features of 8 mammary hamartomas are reported here. RESULTS: The patients are ranged in age from 34 to 67 years. The initial manifestation was in all cases a well-circumscribed, soft, palpable breast lump. Mammography was performed in all patients. Other diagnostic procedures used in the diagnosis were Ultrasound, Fine Needle Aspiration Cytology and Needle Core Biopsy. Treatment was tumorectomy. We describe a case of recurrence after excision of the lump in a more aggressive histological form and one patient who presented the coexistence of a mammary hamartoma and an invasive ductal carcinoma. CONCLUSION: Mammary hamartoma is an uncommon breast tumour. It is necessary the correlation between pathology and clinical and radiological findings. We express our management plan for these lesions.

20 years experience in the management of Zenker's diverticulum in a third-level hospital.

Zenker s diverticulum arises in the posterior wall of the pharynx, above the cricopharyngeal muscle, secondary to a functional cricopharyngeal disorder. We describe our experience with the management of Zenker s diverticulum from 1985 to this day in a third-level hospital. We review clinical data from 27 patients (78% males) with a mean age of 60.4 years. The most common clinical manifestations were dysphagia, regurgitation, syalorrhea, cough, and weight loss. All cases were diagnosed using an esophagogram. A diverticulectomy with cricopharingeal myotomy was performed in 74% of patients. Complications developed in 5 cases (21%), and the recurrence rate was 4% (1 of 3 cases, where myotomy was not performed).

Posthemipelvectomy hernia.

We report the case of a white male who underwent a classic hemipelvectomy due to a femur fibrosarcoma with inguinal metastases, which 33 years later, developed into a posthemipelvectomy hernia in the amputation stump that impaired the use of his Canadian prosthesis. The hernia was repaired with a polypropylene mesh in a subaponeurotic position. A seroma was drained in the postoperative and it was only 2 months after the operation that he could use his prosthesis with any difficulty. A year after the operation, the hernia had not recurred. Only seven similar cases have been published, and there are only four cases with details of their correction, two with a mesh as was our case, and the rest with a primary suture of the aponeurotic borders. A brief review of the bibliography is given on this subject.

Breast metastasis of primary colon cancer.

Metastatic tumors to the breast from colon adenocarcinoma are very rare. They are usually indicative of disseminated disease, and the prognosis is poor. Generally, radical operation should be avoided unless needed for palliation. This case report described a patient with breast metastasis from colon adenocarcinoma treated by simple mastectomy.

[Intraparenchymal non-neoplastic residual masses after treatment of large-cell non-Hodgkin's lymphoma with intensive chemotherapy].

We report two patients with large-cell non-Hodgkin's lymphomas who were treated with intensive chemotherapy (MACOP-B), and in whom large isolated intraparenchymal masses (splenic in one case, renal in the other) were found with computed tomography after clinical remission. It was found at surgery that both masses were constituted by acellular necrotic material, without tumoral infiltration and limited by fibrous tissue. The finding of these residual masses in patients in remission raises problems of approach, as they may be nontumoral and not require new therapy. At present, until new radiological or biochemical markers are available, a judicious clinical attitude should be taken, with radiological control of the evolution of the masses and reserving surgery only for those cases with progression, diagnostic doubts, or patient's decision to know his real status.
