Rationale: Breast low-grade adenosquamous carcinoma is an uncommon cancer that has been neglected in genetic and pathophysiological research. Consequently, medical practitioners face challenges in the effective diagnosis and treatment of this condition.
Patient Concerns: We present the case of a 57-year-old Asian female patient who presented with bilateral breast masses on physical examination. Ultrasound and an MRI revealed a highly suspicious malignant mass in her right breast that was completely removed surgically.
Diagnoses: After pathological analysis, the diagnosis was low-grade adenosquamous carcinoma with local high-grade transformation, and some of the tumor components were estrogen receptor positive.
Interventions: The patient underwent appropriate postoperative chemotherapy and achieved a favorable outcome.
Outcomes: During the follow-up period after surgical resection, the patient did not experience any local recurrence or distant metastasis.
Lessons: Owing to the rare combination of estrogen receptor positivity and high-grade progression, this patient also required adjuvant chemotherapy. This enhances the essential foundation for diagnosing and treating this rare disease, and facilitates the implementation of treatment plans.

(1) Low-grade adenosquamous carcinoma (LGASC) is a rare subtype of metaplastic breast carcinoma (MpBC), accounting for fewer than 0.05% of breast cancer cases. Unlike the typically aggressive nature of MpBCs, LGASC is an indolent tumor with an excellent prognosis.

Article Synopsis
- Diagnosing low-grade adenosquamous carcinoma (LGASC) is challenging due to its subtle appearance and similarity to benign conditions, making identification difficult.
- A 53-year-old woman initially diagnosed with a benign growth underwent a wider excision, which unexpectedly revealed LGASC with some expression of estrogen receptors.
- The case underscores the diagnostic difficulties associated with LGASC, particularly when relying on small tissue samples from biopsies.

Article Synopsis
- Sclerosing lesions of the breast are both benign and malignant and can be challenging to diagnose, requiring awareness of key characteristics to avoid misdiagnosis.
- The review highlights nonneoplastic sclerosing lesions, providing details on their clinical presentation, morphology, diagnostic considerations, and necessary immunohistochemical tests.
- It also briefly discusses atypical or neoplastic entities related to these lesions, emphasizing the importance of accurate diagnosis for effective clinical management.
