Poikiloderma may evolve in 2 stages. During the early stage, which typically occurs before 6 months of age, patients present with a photoinduced erythema on the face. The second stage persists throughout life and is characterized by true poikiloderma (atrophy, telangiectasias, and patches of hyper- and hypopigmentation).
Muscle and tendon contractures are also seen in POIKTMP, particularly of the triceps surae. This classically occurs in childhood and can be seen as early as 2 years of age. Muscle weakness occurs in both proximal and distal muscles of the upper and lower extremities.
Patients can develop severe, life-threatening interstitial pulmonary fibrosis 3-4 years after pulmonary symptoms develop. Other features of POIKTMP include short stature, cataracts, pancreatic insufficiency, liver complications, and hematologic abnormalities.
Facial lesions can be cosmetically distressing, while pulmonary symptoms can be potentially fatal in adulthood.

- Also presents with poikiloderma and sparse hair, eyebrows, and/or eyelashes.
- May also have skeletal and/or dental abnormalities, short stature, cataracts, and increased risk for cancers, eg, osteosarcoma.
