Questions: Challenge to

Differential Diagnosis• Do all the patient’s cutaneous manifestations reflect the

same process (Occam’s razor )?

• If there are multiple processes, is there causalityin the

association? (What is primary and what is secondary?)• What is the true nature of the biopsies interpreted as

squamous cell carcinoma? (Could there be an element of pseudoepitheliomatous hyperplasia?)

• What is the role of the patient’s history of “eczema”? • What is the role, if any, of medication-induced

immunosuppression in the pathogenesis?

• To review the remarkably varied clinical

differential diagnosisfor disseminated

ulcerated, verrucous, plaques• To use the clinical and reported pathologic

data to arrive at a most likely diagnosis

• To try to account for the apparentlyevolving morphologyof the lesions

– following an episode of presumed levofloxacin cutaneoushypersensitivity

– with work-up to date notable for skin pathology interpreted assquamous cell carcinomaand laboratory tests showing a positiveANA, positive anti-U1 snRNP, anemia, leukocytosis with a leftshift, and thrombocytosis

– and minimal improvement to treatment with topical and systemicsteroids, topical tacrolimus, systemic hydroxychloroquine, PUVA,oral antibiotics, isotretinoin, and mycophenolate

Synthesis:

Two scenarios

• Separate processes

– Generalized keratoacanthomas/squamous cellcarcinomas as paraneoplastic phenomenon

– Drug rash

– Cutaneous T-cell lymphoma

• Unified process

Aggressive clinical course (median survival 32months)

• Eruptive papules, plaques & tumors with centralulceration & necrosis

• Metastatic spread to spleen, lungs, liver, CNS, oralcavity & rarely to lymph nodes

• Band-like infiltrate of medium-sized pleomorphic Tcells with a CD3+, CD4-, CD8+ phenotype

• Prominent epidermotropism into an acanthoticepidermis with spongiosis and blistering in all stages

Clinical Course

Corey Cutler, MD MPH FRCP(C)

Department of Hematologic Oncology andStem Cell Transplantation

Dana-Farber Cancer Institute

Clinical Course

• Received 8 courses of dose-intense

Cyclophosphamide, Adriamycin, Vincristine and

Prednisone (CHOP-14 x 8)

• Attains 1st Clinical Complete Remission

• Early Relapse – Responds to CHOP again

• Signs of early cutaneous recurrence within weeks

Clinical Course

• Undergoes Fully Ablative Allogeneic Stem

Cell Transplantation from a Matched,

Unrelated Donor

– Cyclophosphamide (1800 mg/m2 x 2)

– Total Body Irradiation (14 Gy in 7 fractions)

• Complete disappearance of all skin lesions

after near total desquamation

Clinical Course

• Day +24: New diffuse erythema – clinicallyand histologically consistent with acuteGraft-vs.-Host Disease (Stage 3 Skin,

Overall Grade IIC)• Responds to prednisone

• During prednisone taper (~day +150), new

plaque-like skin lesions noted over torso,limbs and scalp

Clinical Course

• Biopsy: Slight spongiosis with parakeratosis

and intracorneal pustules consistent with

early evolving psoriasis

• Responsive to topical high-potency

corticosteroid therapy

• Alive, with skin lesions of unknown

significance, day +165

Transplantation for CTCL

• Rarely performed;

• Heterogeneous literature – case reports,

case series(Molina et al , J Clin Onc 2005)

• Varying outcomes

• DFCI experience, n=3; All alive and

disease-free between 165-300 days; Allwith cutaneous GVHD
