What's wrong with this picture? 🤔
Osteoma cutis:
➡️ Focus of bone formation in skin
➡️ May be associated with chronic inflammatory processes (i.e. acne)
🔎 Take a look for yourself: https://kikoxp.com/posts/23863
"Multinucleated melanocytes may mimic malignancy"
✳️ Multinucleation occurs in both benign & malignant melanocytic lesions
✳️ In benign nevi, overlapping nuclei may mimic atypia at low power

What's your diagnosis for one of these lesions? What about if there are multiple?

Hidrocystomas usually don't pose much of a diagnostic challenge (even on a wimpy shave biopsy)
However, it's still nice to see a full excision every once & awhile 😁

53♂️ w/ lesion on oral mucosa
➡️ Which component is neoplastic?
➡️ Is the neoplasm benign or malignant?

💡 Answer: https://kikoxp.com/posts/19808
14♂️ w/ finger mass
This lesion is ______:
➡️ Non-neoplastic
➡️ Benign
➡️ Malignant
🔬 WSI: kikoxp.com/posts/19790
💡 Answer: kikoxp.com/posts/19790
Here’s a tick - caught in the act. Ticks are blood sucking arachnids. This tick has been excised along with the skin it was biting into. The skin biopsy is about 5mm diameter for scale. The tick is the bulbous structure projecting upward from the skin underneath. Look inside and you can see it’s gut.
Below it you can see ulceration and the cavity it’s mouth has created as it burrowed through the epidermis (the outer layer of skin).
There is flanking dermal necrosis and an intense inflammatory reaction (dark purple patches around the cavity composed of aggregates of inflammatory cells).
