Desmoplastic trichoepithelioma

Case 675  15.1.13 (IH Chaudhry)  M 72 lesion on back 

Not the best example 

Case 796  5.7.13 (R. Carr) M 70 cheek.   

Classical, but perineural invasion (can occur rarely) put some off the diagnosis favouring microcystic adnexal carcinoma 

Case 813  30.7.13 (M. Hurt)  M 51 cheek. (*teaching)  

Useful discussion comparing DTE and DTE-like morphoeic BCC.  Ackerman had a list of 26 differentiating features, of which the most useful seem to be: symmetry in DTE; rims of compact collagen around cords in DTE; aggregations of larger size in BCC, not DTE; variations in size and shape in BCC; bizarre shapes in BCC; foci of typical nodular BCC; epithelial keratin-filled cysts in DTE; calcification of keratin cysts in DTE; mitotic figures rare in DTE; nerve and muscle usually not invaded by DTE 

Case 890 15.11.13 (R. Carr) F 75 lip ?BCC 

Case of morphoeic BCC with discussion comparing features with DTE) 

Case 1725   6.1.17 (R. Carr)  F 60 nasal tip (*teaching) 

Intralesional perineural involvement.  Calcification with knife shatter.  Granulomatous reaction. 

Case 2526  12.3.20 (S. Taibjee)  F 34 nose lesion 

Case 2584  2.6.20  (U. Sundram)  F 45 cheek papule 

Typical features, but superficial biopsy only.  Caveat re superficial biopsy made 

Case 2924  21.9.21  (U. Sundram)  F 65 forehead lesion 

Resources/On-line course/Case 174/24.2.12  F  27  tumour cheek

A superficial and mid dermal tumour forming cords and narrow strands of basaloid cells associated with small keratocysts set in a sclerotic stroma. No evidence of ductal differentiation or intracytoplasmic lumen formation is evident
