(dissenting). This is a good example of a workmen’s compensation imbroglio.

The defendant’s doctor’s deposition (Melvin A. Lester) was taken January 30, 1973. At that deposition, the plaintiffs attorney well and thoroughly preserved for review, objections on the admission of the X-ray report:

"Mr. Meckler (Plaintiff's attorney): Who is this x-ray report made by doctor?

"A. Dr. William F. Wanger.

"Mr. Meckler: Well, then I will object to the doctor’s testimony unless he had the x-rays and he was testifying himself as opposed to hearsay from the report of Dr. Wanger.

"Q. (By Mr. Wallace) [Defendant’s attorney]: Doctor, did you use Dr. Wanger’s x-ray report in writing your report and in coming to your final diagnosis with regard to Mr. Rentz?

"A. Yes.

"Mr. Wallace: Okay, your objection has been noted on the record counsel.

"Mr. Meckler: Then I would have to object to the doctor’s testimony as it is based on hearsay according to his own testimony.

"Mr. Wallace: All Right. Your objection has been noted.”

The first mention of enlarged heart immediately follows the above quoted excerpt.

On March 13, 1973, when the testimony before the referee and all depositions had been concluded, Dr. Lester’s deposition was admitted by the referee "subject to the objections contained therein”. At the same time exhibits 2, 3 and 4 which were hospital records from different hospitals were also *255admitted, and these were admitted "under the Business Entry Statute”. There was never any dialogue concerning business entry admissibility on the deposition objections to Dr. Lester’s testimony. There was never any ruling, either by the refereé or by the appeal board.

After receiving the defendant’s brief, the plaintiff, on or about March 26, 1975, filed with the Workmen’s Compensation Appeal Board, a motion to strike certain portions of defendant’s brief on the grounds they were in violation of the business entry rule and not properly in evidence before the appeal board. One of the paragraphs objected to was the paragraph containing Dr. Lester’s testimony about an enlarged heart. Instead of hearing the motion, the appeal board wrote plaintiff’s attorney a letter which I quote:

"We are in receipt of your recently filed motion in the above captioned matter.

"Rather than acting upon same at the present time, the matter will be referred to the panel of Board members to whom this case is eventually assigned. If it is found that defendant is predicating arguments on material not in evidence, those arguments will fall when the case comes under active review.”

The panel to whom the matter was submitted specifically prescinded from considering plaintiff’s objections with the following pronunciamento:

"Plaintiff argues in part that certain hospital records were admitted into evidence upon defendant’s motion for the limited purposes set forth in MCLA 600.2146 and that the matters contained therein may not be used otherwise. Our opinion will studiously avoid all of these areas which plaintiff finds to be objectionable.”

What does that mean? If one reads that far and no *256farther, one would conclude that the appeal board ruled in favor of plaintiff, at least impliedly, on all of these allegedly objectionable matters. However, two pages later the appeal board quotes specifically the testimony of Dr. Lester on which it then bases its finding:

”Q. (By Mr. Wallace): Okay. Now, Doctor, what effect, if any, could the enlarged heart and the arterialsclerotic [sic] heart disease have on the diagnosis of chronic obstructive pulmonary disease, moderate?

"A. When a patient has an inefficiently functioning enlarged heart the back pressure which I alluded to before may lead to abnormal ventilation of the lungs. Again the lungs no longer function adequately.”

The appeal board’s operative finding was as follows:

" * * * Plaintiff’s lung problems are explained on the basis of the enlarged heart problem from which he suffered. This produced his chronic obstructive pulmonary disease and not the work environment. Plaintiff’s problems, we conclude on the basis of Dr. Lester’s testimony, were the product of the natural aging process.”

.. My reading of the record isolates the enlarged heart diagnosis to the X-ray report which Dr. Lester relied on. The plaintiffs doctor did not find an enlarged heart. Another physician whose deposition was taken, who we may consider ¡ as not belonging to either of the parties, also made no finding of an enlarged heart during a 1969 hospitalization.

The majority is in error in reaching the question of whether the radiologist’s report described a physical condition or a medical diagnosis. I do not *257find it so easy to conclude that an enlarged heart is a general description of a physical condition within the Bond v Greenwood, 34 Mich App 41, 43; 190 NW2d 731 (1971), ruling. The referee never faced the issue of whether or not the radiologist’s conclusion was a diagnosis of a medical condition and we should not either. The appeal board erroneously stated that it was avoiding the areas which plaintiff found to be objectionable. The question is not whether the evidence is competent or incompetent. The evidence is outside of the record. The appeal board’s decision was improperly grounded on evidence dehors the record.

I would reverse the appeal board with respect to this finding and reinstate the decision of the referee in all respects as I find no other evidence, competent, material or otherwise, to support the appeal board’s ruling except that evidence it expressly discarded.

Plaintiff appeals by leave from a June 27, 1975, decision and order of the Work*251men’s Compensation Appeal Board, reversing the order of the hearing referee, that had awarded plaintiff $10,500 plus interest for a compensable lung disability.

Plaintiff’s appellate arguments are directed solely to a substantive question of evidence. Plaintiff argues that the decision of the board is not based on competent evidence, because the decision is grounded on a doctor’s deposition testimony, which in turn was partially based on a fellow doctor’s written report accompanying an X-ray of plaintiff’s heart. We need concern ourselves only with the substantive propriety of the board’s consideration of the deposed doctor’s reliance on the report. The parties do not raise, nor need we address, any procedural irregularities allegedly arising in the board’s consideration of the evidence.1

As part of the proceedings, defendant introduced the deposition of Dr. Melvin Lester. Dr. Lester concluded that plaintiff’s lung condition was attributable to a natural degeneration of plaintiff’s heart, the result of his 74 years of life, rather than due to any impurities in his working atmosphere. In reaching his conclusion, Dr. Lester referred to a report accompanying an X-ray of plaintiff’s heart. The report was prepared by the doctor taking the X-ray, a Dr. Wanger, a staff member of a clinic supervised by Dr. Lester. The report contained Dr. Wanger’s description of plaintiff’s heart as "enlarged”. Dr. Lester referred to this description in stating his proposed etiology of plaintiff’s ailments.

Plaintiff claims that Dr. Lester’s opinion, and hence the board decision, must fall because Dr. *252Lester’s opinion was based on inadmissible hearsay, i.e., Wanger’s report. However, Bond v Greenwood, 34 Mich App 41, 43; 190 NW2d 731 (1971), clearly establishes that in judicial proceedings, a hospital record is admissible as a business entry under MCLA 600.2146; MSA 27A.2146 if the record contains "a general description of a physical condition, as distinguished from a diagnosis”. 34 Mich App at 43. The present report, made by a member of the staff supervised by Dr. Lester, is not a diagnosis but a statement of physical condition. A diagnosis is the "discovery of the source of a patient’s illness or the determination of the nature of his disease from a study of the symptoms”. Black’s Law Dictionary (4th ed), 540.2 "Enlarged” says little about etiology and is more properly considered a factual adjective, albeit requiring some perceptual approximation. Most physical descriptions require some degree of perceptual flexibility.3

We note that in Wade v Bay City, 57 Mich App 581; 226 NW2d 569 (1975), this Court ruled inadmissible as a diagnosis an X-ray report that concluded " 'we have no X-ray evidence of bone or joint pathology of recent traumatic origin’”, 57 Mich App at 583. That report clearly suggests an etiology, a source, an analysis; the present report does not.

*253A further point may be made. Bond and Wade discuss hospital report hearsay in a judicial setting. It is now established that evidentiary rulings in administrative proceedings may stray from rigid courtroom rules on evidence. E.g., Viculin v Department of Civil Service, 386 Mich 375, 403; 192 NW2d 449 (1971). In fact, in contested cases before an administrative agency, a fact-finder may admit and give probative effect to "evidence of a type commonly relied upon by reasonably prudent men in the conduct of their affairs”. MCLA 24.275; MSA 3.560 (175). Should not then a reasonably prudent person feel safe in relying on and finding relevance in the description "enlarged heart” issued by a physician, particularly when the physician’s supervisor-doctor is present to answer questions about the X-ray procedures employed by the clinic? If a doctor would rely on the X-ray report, can it be said that a reasonably prudent person would not?4

Finally, we note that the board accepted the credible testimony of a plant foreman, familiar with plaintiff’s working area, that there was no atmospheric debris in plaintiff’s area. This testimony supports, if not establishes, the defense that plaintiff experienced breathing ailments because of his age. Our examination of this record indicates that the decision of the Workmen’s Compensation Appeal Board was based on competent, material and substantial evidence. Gilbert v Reynolds Metals Co, 59 Mich App 62; 228 NW2d 542 (1975).
