A Practical Guide to Feline Dermatology

Configuration of lesions

Determining the configuration of lesions is much morę difficult in the cat due to its dense coat. Nevertheless, the following arrangements may be recognised: punctate, lenticular, nummular (coin-shaped), annular, linear and arciform (ring-shaped)¹⁴¹⁵ (Table 2 : 2).

Lesion distribution

Assessing the distribution of lesions is the finał step in the dermatological examination ^Ul4,15 (Table 2:3). It provides essential information as many conditions have specific distribution pattems (Table 2 : 4). However, these pattems may change as a dermatosis progresses. They may also be modified by various treatments. The initial distribution pattem may be very different to the one seen in the consulting room.
