It states the following about pyromania:
Pyromania is characterised by a recurrent failure to control strong impulses to set fires, resulting in multiple acts of, or attempts at, setting fire to property or other objects, in the absence of an apparent motive (e.g., monetary gain, revenge, sabotage, political statement, attracting attention or recognition). There is an increasing sense of tension or affective arousal prior to instances of fire setting, persistent fascination or preoccupation with fire and related stimuli (e.g., watching fires, building fires, fascination with firefighting equipment), and a sense of pleasure, excitement, relief or gratification during, and immediately after the act of setting the fire, witnessing its effects, or participating in its aftermath. It also notes that pyromania has no relation to intellectual impairment, substance abuse, or other mental and behavioral disorder. ICD-11 was produced by professionals from 55 countries out of the 90 countries involved and is one of the most widely used reference worldwide by clinicians, with the other being the Diagnostic and Statistical Manual of Mental Disorders (DSM-5-TR from 2022, DSM-5 from 2013, or their predecessors)

DSM
The American Psychiatric Associations Diagnostic and Statistical Manual of Mental Disorders, First Edition, released in 1952, categorized pyromania as a subset of Obsessive–compulsive disorder. In the Second Edition, the disorder was dropped. In the Third Edition, it returned under the category of impulse-control disorders.The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, Text Revision (DSM-5-TR), released in 2022, states that the essential feature of pyromania is "the presence of multiple episodes of deliberate and purposeful fire setting."
Pediculosis corporis is a cutaneous condition caused by body lice (specifically Pediculus humanus humanus) that lay their eggs in the seams of clothing. : 447

Signs and symptoms
Body lice are a nuisance in themselves and cause intense itching. They are also vectors (transmitters) of other diseases and can spread epidemic typhus, trench fever, and louse-borne relapsing fever. Risk factors
Body lice are spread through prolonged direct physical contact with a person who has them or through contact with articles such as clothing, beds, bed linens, or towels that have been in contact with an infested person. In the United States, body lice infestations are rare, typically found mainly in homeless transient populations who do not have access to bathing and regular changes of clean clothes. Infestation is unlikely to persist on anyone who bathes regularly and who has at least weekly access to freshly laundered clothing and bedding.Although louse-borne (epidemic) typhus is no longer widespread, outbreaks of this disease still occur during times of war, civil unrest, natural or man-made disasters, and in prisons where people live together in unsanitary conditions. Louse-borne typhus still exists in places where climate, chronic poverty, and social customs or war and social upheaval prevent regular changes and laundering of clothing. Pathophysiology
Body lice frequently lay their eggs on or near the seams of clothing. They must feed on blood and usually only move to the skin to feed.
