Pregnancy-associated breast cancer (PABC) is defined as cancer of the breast diagnosed during pregnancy and up to 1 year postpartum. The crude incidence is 1/3000 pregnant women. As women delay childbearing the incidence of PABC increases with age. Young patients with PABC do not have worse prognosis compared with those with non-PABC; however, pregnancy can contribute to a delay in breast cancer diagnosis, evaluation, and treatment. Primary care physicians and gynecologists should be careful in the thorough workup of breast symptoms in the pregnant population to expedite diagnosis and allow multidisciplinary treatment as early as possible following the established diagnosis. Authors report a case of a 30-year-old pregnant woman, who detected inflammatory signs of her right breast and a palpable axillary mass at the 21st week of gestation. Her symptoms did not improve with administration of antibiotics. Therefore fine needle aspiration biopsy of the axillary lump was performed, with the result of unequivocal diagnosis of metastatic invasive carcinoma. The patient was referred to the multidisciplinary tumor board of our Department at the 27st week of gestation with the symptoms of inflammatory breast cancer, palpable right axillary and supraclavicular lymph nodes. Core biopsy showed an ER and PR negative, Her-2 positive, grade 3, infiltrating ductal carcinoma of the breast. After multidisciplinary team consultation the patient declined any kind of therapy during her pregnancy. On the 30th week of gestation caesarean section was performed. The premature baby girl was treated in the Neonatal Intensive Care Unit. Imaging modalities revealed no evidence of distant metastases short after the delivery. After 6 cycles of chemotherapy (docetaxel-doxorubicin-cycclophosphamid) the patient underwent right mastectomy and axillary lymph node dissection. Complete pathological response was diagnosed, since no residual tumor was found in the surgical resection specimen. After radiotherapy, trastuzumab medication was initiated. To date, there is no evidence of local recurrence or distant metastases during her 24 months follow-up. The newborn is on close neurohabilitation follow-up due to the evidence of generalized muscle dystonia. Had the patient accepted chemotherapy, the damage of the newborn baby would have been avoidable.

Neuroblastoma is the most common solid extracranial malignancy diagnosed in childhood. Clinical presentation is variable, and metastatic disease is common at diagnosis. Analyses of urinary catecholamines and their metabolites are commonly requested as a first-line investigation when clinical suspicion exists. Levodopa (L-Dopa) therapy is utilized as a treatment for a number of disorders in childhood, including Dopa-responsive dystonia. Neuroblastoma may mimic some of the clinical features of this disorder. L-Dopa can interfere with analysis of urinary catecholamines and their metabolites and complicate the interpretation of results. We present the cases of three children who were prescribed L-dopa at the time of analysis of urinary catecholamines and metabolites as a screen for neuroblastoma, but who did not have the disease. Comparison of their results with those from cases with true neuroblastoma reveal that it is impossible to reliably distinguish true neuroblastoma from L-Dopa therapy using these tests. We recommend that patients should be off L-dopa therapy, if possible when these tests are performed. These cases illustrate the importance of providing clinical details and drug history to the laboratory in order to avoid diagnostic confusion.
