Smooth Muscle Hamartoma 👶👶🔬✏️ ✔️Rare ✔️Congenital lesion ✔️flesh colored plaque ✔️Composed of randomly arranged bundles of mature smooth muscle in the dermis ✔️overlying epidermis may show hyperkeratosis, acanthosis and hyperpigmentation #pathology #dermpath #PediPath

What an incredible case! Young woman had innumerable flesh colored papules and nodules obliterating her nose and involving most of her central face. Trichoepithelioma - basaloid tumor islands, keratin filled cysts, fibrotic stroma, abortive follicles #dermpath

It’s a very nice case of Clear Cell Papillary RCC with clear cells with linearly-arranged low grade nuclei toward luminal surface in a tubular/acinar or papillary architecture. Cup-shaped CAIX & CK7 positive. Can be associated with ESRD or sporadic. Indolent prognosis #GUpath

Clear cell acanthoma. Red papule. Epidermal acanthosis (similar to seb ker) with pale cells. Peppered with neutrophils (arrow). Sharp demarcation from normal skin. Frequently spiraled vessels in the pap dermis. Clear cells due to glycogen. #dermatology #dermpath #pathology

Ever wondered how well clinically measured surgical margins correlate with histologic margins in #melanoma: not that well is the answer! Neat study driven by surgical and pathology fellows from Melanoma Institute Australia just published. #dermpath #pathology #surgery

Senior Pathology residents in the gross room (#GrossPath) on the Wednesday afternoon before Thanksgiving be like:

Inverted follicular keratosis with a bonus: BIG scattered pigmented dendritic melanocytes! They’re just “passengers” along for the ride. Not melanoma. Evenly spread out in the keratinocytic lesion. Can see these in BCC, SCC, SK, adnexal, etc. #dermpath #Pathology #dermatology

Hailey-Hailey disease with the so-called dilapidated brick wall. ATP2C1 mutation. Intertriginous bullae. Intraepidermal acantholysis. Clinical correlation to differentiate from other acantholytic dermatoses. #dermpath #pathogy #dermatology

Myxofibrosarcoma. Hypocellular myxoid areas w scattered atypical cells. Long curvilinear vessels. Solid zones resembling undiff. pleomorphic #sarcoma. Extremities of elderly. 50% involve skin/subcutis. My video: buff.ly/2D9iuet #pathology #BSTpath #meded #dermpath

Diagnosis: Staph scalded skin syndrome. SSSS (not SJS/TEN). Detached stratum corneum w free floating acantholytic keratinocytes (key to dx!). If corneum missing look around slide to try to find it. No inflammation or bacteria (toxin mediated). #dermpath #Pathology #dermatology

An incidental well-circumscribed 2 cm mass in the bladder wall. Low power the mass is composed of a well demarcated spindle cell neoplasm. Higher power reveals mild atypia & perinuclear vacuoles. No mitosis or necrosis. Positive for desmin and SMA. Dx: leiomyoma #GUpath

A 40-year-old male presented with nasal polyp extending from lateral nasal wall. A very nice case of the least common subtype of oncocytic papilloma. I am trying a little bit #flashcard style inspired by I Heart Pathology.

Happy Valentine’s Day #dermpath #PathArt

I tried to do a flashcard to summarize what we need to know about osteochondroma. This 2-year-old has multiple osteochondromas and positive family history too. #bonepath #UTMB

“I feel like we were in a little bit of denial,” says Mitchell, South Dakota, Councilwoman Susan Tjarks, a Republican who faced criticism for proposing a mask mandate. “This isn’t a political issue, it’s not a Democrat virus and it’s not a Republican virus.”
