ABSTRACT

Introduction. Mammary hamartomas are rare benignbreast lumps. They are usually painless, wellcircumscribed,mobile and with no adherence toskin or muscle, composed of varying amounts offat, glandular and fibrous tissue. Mammary hamartomahas been classically considered as an underdiagnosedpathology, but with the increasing use ofdiagnostic procedures in breast tumours, the numberof hamartomas has increased in the last years.Because there is no distinct pathological feature, acorrelation with the clinical findings and imagetechniques is necessary in order to achieve a correctdiagnosis of the pathology.Materials and methods. The clinicopathologicalfeatures of 8 mammary hamartomas are reportedhere.Results. The patients are ranged in age from 34 to67 years. The initial manifestation was in all cases awell-circumscribed, soft, palpable breast lump.Mammography was performed in all patients. Otherdiagnostic procedures used in the diagnosis wereUltrasound, Fine Needle Aspiration Cytology andNeedle Core Biopsy. Treatment was tumourectomy.We describe a case of recurrence after excision ofthe lump in a more aggressive histological formand one patient who presented the coexistence of amammary hamartoma and an invasive ductal carcinoma.Conclusion. Mammary hamartoma is an uncommonbreast tumour. It is necessary the correlationbetween pathology and clinical and radiologicalfindings. We express our management plan forthese lesions
