Overview
Historical Perspective
- Papa syndrome was first discovered by Dr. Noralane M. Lindor, in 1997 following visiting several patients from three generations of a family with similar presentations.[1]
- The association between PSTPIP1 gene mutation and Papa syndrome was made in the year 2000.[2]
Classification
- There is no established system for the classification of Papa syndrome.
Pathophysiology

OR
[Pathogen name] is usually transmitted via the [transmission route] route to the human host.

Causes
Papa syndrome is caused by a mutation in the PSTPIP1 gene.[2]
Differentiating ((Page name)) from Other Diseases

Diagnosis
Diagnostic Study of Choice
- There are no established criteria for the diagnosis of Papa syndrome. The diagnosis may be made clinically.
- Genetic analysis and location of a mutation in the PSTPIP1 gene may be done for the confirmation of the diagnosis. However, there are reported cases of Papa syndrome with negative genetic results.
History and Symptoms
- A positive history of recurrent arthritis, skin ulceration, and acne is suggestive of Papa syndrome.
- The presenting symptom of Papa syndrome is usually culture-negative arthritis.
Physical Examination
- Physical examination of patients with Papa syndrome is usually remarkable for arthritis, cystic acne, and pyoderma gangeronosum.
Laboratory Findings
- Laboratory findings consistent with the diagnosis of Papa syndrome include elevated serum levels of C-reactive protein (CRP), Erythrocyte sedimentation rate (ESR), and WBC.
Electrocardiogram
- There are no ECG findings associated with Papa syndrome.
X-ray
There are no x-ray findings associated with [disease name].
OR

OR
There are no x-ray findings associated with [disease name]. However, an x-ray may be helpful in the diagnosis of complications of [disease name], which include [complication 1], [complication 2], and [complication 3].
Echocardiography or Ultrasound
There are no echocardiography/ultrasound findings associated with [disease name].

OR
There are no MRI findings associated with [disease name]. However, a MRI may be helpful in the diagnosis of complications of [disease name], which include [complication 1], [complication 2], and [complication 3].
Other Imaging Findings
