Introduction

Mrs. N, A 20year old, breast feeding mother of one child of one year, presented with gradual onset of spontaneous reduction in right sided breast size since one month of commencement of breast feeding which was noticed by herself. She was healthy in the past and had no significant medical or endocrine illnesses to note. There was no associated pain or numbness over the chest region and there was no history suggestive of chest wall trauma, radiation or surgery in the past. She claimed that her breast development was normal and equal which was confirmed with a past photography. This was the first pregnancy for her. Since the birth of her baby she breast feeds from both breasts and the milk production from both breasts were equal despite the smaller size of right breast. There was no history of febrile illness associated with rash and lymphadenopathy in the recent past. She resumed her normal menstrual cycles after two months of normal vaginal delivery and currently on implant contraceptive method. Prior to this her menstrual cycles were regular and there was no history of menorrhagia or oligomenorrhoea. She never used any hormonal contraceptive methods except the current practice. She is a house wife, has no pets at home. She is a non-smoker and uses no alcohol or illicit drugs. There was no similar kind of problems in her family. The examination revealed an obvious un-equality between both breasts with smaller right breast. The nipples were noted to be everted and areolar components were similar in appearance and size in both sides. Both breasts were engorged but comparatively lesser in right side. There were no overlying skin changes, fibrosis nor palpable lumps in either side. Both breasts were non tender and normal in consistency. Milk expression was equal. The baseline full count, inflammatory markers, renal and liver profile were noted to be normal. The thyroid function test was normal. An Ultrasound scan of breasts revealed normal looking breast tissues with features of lactation in ducts. There were no masses or axillary lymphadenopathy noted. Except for asymmetry in size it was concluded that the right breast was ultrasonically normal. She was reassured and reviewed in six months with comparison of anthropometric measurements, where no differences were noted, neither improvement nor further reduction. The patient has not consented for breast reconstructive surgery.

Discussion

Conditions like acquired idiopathic unilateral breast atrophy in previously normally developed breasts without any known etiological factor is seldom reported in the literature. This is the second case that we present as idiopathic breast atrophy [1]. There was another case report on unilateral breast atrophy, subsequent to infectious mononucleosis infection [2]. Otherwise the current evidences exist are mainly on bilateral breasts atrophy following hormonal alterations associated with either menopause or anti androgen treatments [3].
