UNASSIGNED: Spontaneous @entity1188 is a rare condition associated with the physiological hyperplasia of breast tissue associated with pregnancy and lactation. The causes of and mechanism underlying the occurrence of this complication remain largely unknown. The present study describes a rare case of @entity0 occurring during pregnancy and lactation in a 20-year-old @entity1 . At 2 months of gestation, the @entity1 noticed a soft and painless lump (size, ~5*4 cm) in the right breast. The lump grew to eventually occupy the entire breast. The @entity1 was hospitalized 1 month after delivery and underwent a mastectomy. Histopathological study of the resected breast tissue revealed that 90% of the breast tissue had undergone @entity1188 , with the @entity1188 located centrally, under the areola. Involution of the breast tissue and small focal @entity548 were noted, along with acute or chronic inflammatory cell infiltration in the interstitial tissue. Some breast ducts showed @entity384 , while some small blood vessels showed dilatation and congestion. Postoperative recovery of the @entity1 was uneventful. This was a case of @entity0 with irregular, high-grade fever. The findings of core-biopsy were inconclusive, which highlights the importance of Mammotome    biopsy or surgical excision in the diagnosis in such cases.
