The classification of cutaneous lymphomas is multidisciplinary and requires the correlation between clinical, histopathological, immunohistochemical, and molecular diagnostic elements. In this article, we present four different cases of CD30-positive T-cell lymphoma with cutaneous manifestations. We compare cases with definitive diagnosis of papulosis lymphomatoid type C, primary cutaneous anap...

Anaplastic large cell lymphomas (ALCLs) are a group of CD30 positive T-cell non-Hodgkin lymphomas, accounting for only 3% all lymphomas. As per the 2017 World Health Organization updated classification, there four variants ALCL: anaplastic lymphoma kinase (ALK) positive, ALK negative, primary cutaneous, and breast-implant associated. The different ALCL share overlapping clinical presentations p...

Summary This year’s virtual version of the European Society for Medical Oncology (ESMO) presidential sessions included three “late breaking” non-small cell lung cancer (NSCLC) abstracts, discussing strategies adjuvant therapy localized disease and up-front treatment advanced anaplastic lymphoma kinase(ALK)-positive cancer.

A 56-year-old woman presented with a mixed-grade oligodendroglioma. On 11C-methionine [MET]-positron-emission tomography images, heterogeneous uptake of MET was demonstrated in the mass lesion. The part of the lesion with higher MET uptake was identified as an ordinary oligodendroglioma, whereas the part of the lesion with lower MET uptake was an anaplastic component of oligodendroglioma. With ...

In general it is fairly true to say that the prognosis in anaplastic malignant tumours of the soft tissues of the skeletal muscles is poor, but surprising exceptions do occasionally occur. The following two cases are examples of such exceptions and are reported because of their unexpected, long, and recurrence-free survival after local excision only. Both were rapidly growing, highly anaplastic...

Anaplastic large T-cell lymphoma is a very rare disease in childhood. The most common locations are lymph nodes and skin, while the external ear location is uncommon. We present the case of a 6-year-old child with an earlobe tumour. Surgical treatment was performed and the anatomopathological results showed anaplastic large cell lymphoma. Radiological tests were negative and there was no system...

A 64-year-old man was referred to our hospital because of persistent dyspnoea for the past 1 month. He had recurrent brain anaplastic meningioma after two operations and irradiation. He suffered from right pleural effusion in the previous few months and was diagnosed with malignant mesothelioma via pleural biopsy 1 month prior to coming to our hospital. At his first visit to our hospital, thora...
