Just back from a wonderful meeting of the Mexican Academy of Dermatology arranged by Marcela Saeb. A truly great meeting with the very best of South American dermatopathologists. Congratulations to Marcela. This is a difficult case but Juan Carlos is quite correct. The diagnosis is a desmoid fibromatosis. The figure in the bottom left shows a fascicular growth pattern and the bottom right shows the typical bland cytology. Nodular fasciitis is an excellent differential diagnosis althoug if this had been the diagnosis I would have included a picture of feathery myxoid change. Desmoplastic melanoma could have also been included in the differential diagnosis. Exciting news, I have recently heard that the 4th edition of Patholohy of the Skin will be published in August of this year.

Good morning. I like more for some kind of fibromatosis. Although there is a myxoid stroma I dont see really a tissue culture like, nor hemorrahage or mitosis

I will go for nodular fasciitis. I think the "tissue culture-like" pattern of nodular fasciitis is presented in the third picture(to the left) and I cant see the honey coomb infiltration of SC fat characteristic of DFSP.

Difficult as usual when it comes to spindle cell neoplasma. However, I can c extravasated RBC's and focal lymphocytic infiltrate. Together with the myxoid background with fenestrated feathery appearance mostly apparent in the last image, my first impression is nodular fasciitis..It also affects upper extremities mainly.DDx: myxoid DFSP.
