Congratulations Kate although I did give rather a lot of help on that one!! I did query collagenomas / benign fibromas in my original report but I commented on the lichenification and asked about frictional trauma at our clinicopathological meeting. It was only subsequent to this we got the history that in his job re-stocking shelves in a supermarket he was often on his knees with his feet flexed against his footware. Similar lesions have been referred quite rightly as prayer nodules, athlete's nodules, surfer's nodules etc The keratosis pilaris was just part of the history and a total red herring! Regards to all.

So, agree with Eman. The aswer must be '' acquired knuckle pads of the feet associated with repetitive friction with athletic gear ''

If the correct answer is athlete's nodule, then why you said ''not collagenomas'' (CTN) ! Isn't it sports-related connective tissue nevi of the collagen type ?

Agree with Dr. Abdul-kadir as 'Athlete's nodules. Cohen PR, Eliezri YD, Silvers DN. Cutis. 1992 Aug;50(2):131-5', which fits well with clinical and histopathological features.

My apologies for missing the history. The biopsy site is either of dorsal feet or knee, other than the plantar surface. The hairy plam sign as a clue for lichen simplex or frictional dermatosis related to sports activities?

Okay I need to be a little more helpful - perhaps you could pray for help? - think Olympics - AND note the LICHENIFICATION! You could SURF the internet. The swellings were on the dorsal feet and knees.

Maybe the lesions on thighs and arms are related with Darier disease, that can be confused with keratosis pilaris, clinically.

Not collagenomas. Clues are anatomical locations and the overlying changes. Good Luck Engin!!!
