Differential diagnosis
There are several mental disorders in the DSM-5 that are listed as differential diagnoses for OCPD. They are as follows:

Obsessive–compulsive disorder. OCD and OCPD have a similar name which may cause confusion; however, OCD can be easily distinguished from OCPD: OCPD is not characterized by true obsessions or compulsions. Hoarding disorder. A diagnosis of hoarding disorder is only considered when the hoarding behavior exhibited is causing severe impairment in the functioning of the person, such as an inability to access rooms in a house due to excessive hoarding. Narcissistic personality disorder. Individuals with a narcissistic personality disorder usually believe that they have achieved perfection (especially compared to other people) and cannot get better, whereas those with OCPD do not believe that they have achieved perfection, and are self-critical. Those with NPD tend to be stingy and lack generosity; however, they are usually generous when spending on themselves, unlike those with OCPD who hoard money and are miserly on themselves and others. Antisocial personality disorder. Similarly, individuals with antisocial personality disorder are not generous, but miserly around others, although they usually over-indulge themselves and are sometimes reckless in spending. Schizoid personality disorder. Schizoid personality disorder and obsessive-compulsive personality disorder may both display restricted affectivity and coldness; however, in OCPD, this is usually due to a controlling attitude, whereas, in SPD, it occurs due to a lack of ability to experience emotion and display affection. Other personality traits. Obsessive-compulsive personality traits may be particularly useful and helpful, especially in productive environments.
Post-surgical breast hematomas can also impede wound healing and therefore impact the cosmetic outcome. Hematomas are furthermore one of the risk factors for breast surgical site infections. There is preliminary evidence that, after breast implant surgery, the presence of hematoma increases the risk of developing capsular contracture.In mammography screening, scar tissue resulting from a breast hematoma can easily be confused with tumor tissue, especially in the first years following surgery. Ultimately, fat necrosis may occur in the concerned region of the breast. Diagnosis
When there is post-operative swelling after breast surgery or core needle biopsy, a breast ultrasound examination may be indicated in order to differentiate between a hematoma and other possible post-surgical complications such as abscess or seroma, A recent hematoma is usually visible in a mammogram. and it also shows typical signal intensities on MR imaging. If a differentiation from breast cancer is necessary, a hematoma biopsy may be indicated. A careful consideration of the case history is important for the diagnosis of a breast hematoma. Treatment
Small breast hematomas that cause no discomfort often require merely clinical observation, with ultrasound being used to monitor the resolution of the hematoma. Large breast hematomas, or those that are not becoming smaller or that are causing discomfort, usually require drainage. Also hematomas that occur after surgery for excision of a malignant tumor are drained, because a hematoma to which irradiation is applied is unlikely to ever resolve. A recent hematoma can be drained by means of needle aspiration or (rarely) open surgical drainage. References
