23-Year-Old Female with an Inflammatory Myofibroblastic Tumour of the Breast: A Case Report and a Review of the Literature.

ABSTRACT: Purpose: Inflammatory myofibroblastic tumours (IMT) are a subcategory of inflammatory pseudotumours (IPT). They arise most commonly in the abdominopelvic region, lung and retroperitoneum, but virtually any anatomical site may be involved. Predominantly children and adolescents are affected and there is a tendency for local recurrence. In the literature up to the present, 20 patients have been reported with an IPT/IMT of the breast. We would like to present another patient with this unusual tumour entity of the breast and discuss the literature. Patient and Examinations: A 23-year-old woman presented with a painless lump in her left breast. There was no history of breast cancer in her family. Sonography showed a hypoechoic heterogeneous solid mass with irregular margins. A core needle biopsy revealed a tumour of high cellularity and a densely collagenous background. Immunohistochemically, the spindle-shaped cells were immunoreactive to smooth muscle actin and ALK-1 protein. Additional FISH analysis proved ALK rearrangements on chromosome 2p23 leading to the diagnosis of an IMT. Wide surgical excision was performed with no evidence of local recurrence after 12 months. Conclusion: Three of the above mentioned 20 patients with IMT/IPT of the breast developed a recurrent tumour, none presented with distant metastasis. A significant recurrence rate of 15 % leads to a clinically and sonographically close follow-up in these patients.

Project description:The International Headache Society (IHS) defines ophthalmoplegic migraine (OM) as recurrent attacks of headache with migrainous characteristics, associated with paresis of one or more ocular cranial nerves (commonly the third cranial nerve), and in the absence of any demonstrable intracranial lesion other than MRI changes within the affected nerve. According to the IHS criteria, it is diagnosed when at least two attacks with migraine-like headaches are accompanied with, or followed within 4 days of onset by, paresis of one or more of the third, fourth or sixth cranial nerves. Parasellar, orbital fissure and posterior fossa lesions should be ruled out by appropriate investigations. It is unlikely that OM is a variant of migraine, since the headache often lasts for a week or more and there is a latent period of up to 4 days from the onset of headache to the onset of ophthalmoplegia. Furthermore, in some cases MRI shows gadolinium uptake in the cisternal part of the affected cranial nerve and this suggests that the condition may be a recurrent demyelinating neuropathy. In general, patients demonstrated a: (1) prolonged time for symptom resolution to occur (median time 3 weeks); (2) tendency for recurrent episodes to have more severe and persistent nerve involvement; (3) evidence of permanent neurological sequelae with recurrent episodes (30% of patients); (4) rapid improvement and shortened duration with corticosteroid therapy and; (5) transient, reversible MRI contrast enhancement of the affected cranial nerve (86% of patients). Different pathogenetic mechanisms, which include compressive, ischemic and inflammatory, have been suggested for OM. Here, a 15-year-old Ethiopian with recurrent attacks of headache and third nerve palsy is presented. The subsequent discussion focuses on current evidences with regard to the clinical characteristics, possible pathogenetic mechanisms and treatment. Finally, a brief discussion of the situation in Africa will be presented.
