Pigmented Dermatofibrosarcoma (bednar Tumour) of Scalp.
BMJ CASE REPORTS（2023）

Abstract
Pigmented dermatofibrosarcoma protuberans (DFSP) also known as Bednar tumour is a very rare variant of DFSP which is considered to be of intermediate grade along with the presence of melanin-containing dendritic cells. Only a handful of cases have been described in the literature so far. It is centred around the dermis or subcutis and can pose a diagnostic challenge by being confused with other pigmented lesions of the skin. We hereby report one such unusual case of a man in his late 20s presenting with swelling over the forehead for the past 7 years. Hence a diagnosis of pigmented DFSP should always be considered while reporting pigmented subcutaneous lesions with spindle cell morphology.

- Pretraining has recently greatly promoted the development of natural language processing (NLP)
- We show that M6 outperforms the baselines in multimodal downstream tasks, and the large M6 with 10 parameters can reach a better performance
- We propose a method called M6 that is able to process information of multiple modalities and perform both single-modal and cross-modal understanding and generation
- The model is scaled to large model with 10 billion parameters with sophisticated deployment, and the 10 -parameter M6-large is the largest pretrained model in Chinese
- Experimental results show that our proposed M6 outperforms the baseline in a number of downstream tasks concerning both single modality and multiple modalities We will continue the pretraining of extremely large models by increasing data to explore the limit of its performance
